Abstract: Aurora kinases are a family of serine/threonine kinases vital for cell division. Because of the overexpression of Aurora kinases in a broad range of cancers and their important roles in mitosis, inhibitors targeting Aurora kinases have attracted attention in cancer therapy. VX-680 is an effective pan-Aurora kinase inhibitor; however, its clin. efficacy was not satisfying. In this study, we performed CRISPR/Cas9 screens to identify genes whose depletion shows synthetic lethality with VX-680. The top hit from these screens was GSG2 (also known as Haspin), a serine/threonine kinase that phosphorylates histone H3 at Thr-3 during mitosis. Moreover, both Haspin knockout and Haspin inhibitor-treated HCT116 cells were hypersensitive to VX-680. Furthermore, we showed that the synthetic lethal interaction between Haspin depletion and VX-680 was mediated by the inhibition of Haspin with Aurora kinase B (AURKB), but not with Aurora kinase A (AURKA). Strikingly, combined inhibition of Haspin and AURKB had a better efficacy than single-agent treatment in both head and neck squamous cell carcinoma and non-small cell lung cancer. Taken together, our findings have uncovered a synthetic lethal interaction between AURKB and Haspin, which provides a strong rationale for this combination therapy for cancer patients. This study involved multiple reactions and reactants, such as (2R,3R,4S,5R)-2-(4-Amino-5-iodo-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-5-(hydroxymethyl)tetrahydrofuran-3,4-diol (cas: 24386-93-4Electric Literature of C11H13IN4O4).

Solid acid catalysis, and the advantages often associated with their use, have been proved equally efficient for the synthesis of tetrahydrofurans or furans.

The omicron (B.1.1.529) variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is responsible for coronavirus disease 2019 (Covid-19), has spread rapidly around the world and has already become the predominant variant circulating in many countries. As compared with the Wuhan/Hu-1/2019 reference strain, the sublineage BA.2 of the omicron variant has 16 amino acid substitutions in the receptor-binding domain of the spike (S) protein of SARS-CoV-2, which is the primary target for monoclonal antibody-based therapy. These findings suggest that there may be differences in the effectiveness of monoclonal antibodies against these different omicron sub-lineages. The susceptibilities of omicron/BA.2 (NCD1288) to remdesivir, molnupiravir, and nirmatrelvir were similar to those of the ancestral strain and other variants of concern (i.e., 50% inhibitory concentration values for these three agents that differed by factors of 2.5 to 4.5, 0.7 to 1.6, and 1.5 to 3.3, resp.). Clin. studies are warranted to determine whether these antiviral therapies are indeed effective against omicron/BA.2 infections. Our data indicate that some therapeutic monoclonal antibodies (REGN10987-REGN10933, COV2-2196-COV2-2130, and S309) have lower neutralizing activity against omicron/BA.2 than against earlier variant strains. This study involved multiple reactions and reactants, such as ((2R,3S,4R,5R)-3,4-Dihydroxy-5-((Z)-4-(hydroxyimino)-2-oxo-3,4-dihydropyrimidin-1(2H)-yl)tetrahydrofuran-2-yl)methyl isobutyrate (cas: 2492423-29-5Reference of 2492423-29-5).

A review. Since the first outbreak in late 2019, the RNA genome of SARSCoV-2 has been undergoing constant evolution. This is largely attributed to the viral polymerase that is intrinsically error prone and the selection pressures exerted by the host immune system. Several variants of concern harboring multiple mutations in the spike protein have emerged in the past year. The currently fast-spreading Omicron variant contains many more mutations compared with the previous variants, and most of these mutations are located around the receptor binding domain of the spike protein. This would dramatically, although not completely, compromise the efficacy of the existing COVID-19 vaccines. In summary, this study has demonstrated that molnupiravir and nirmatrelvir potently inhibited the infection of SARS-CoV-2 Omicron variant. Combination of molnupiravir and nirmatrelvir exerted synergistic antiviral activity. Of note, there are some subtle differences regarding the patterns of antiviral response among WT, Omicron and Delta variants, as well as between cell line and organoid models. Nevertheless, our findings support the use of molnupiravir and nirmatrelvir for treating Omicron-infected patients. We further call the initiation of clin. studies to evaluate the combination of molnupiravir and nirmatrelvir for treating COVID-19. This study involved multiple reactions and reactants, such as ((2R,3S,4R,5R)-3,4-Dihydroxy-5-((Z)-4-(hydroxyimino)-2-oxo-3,4-dihydropyrimidin-1(2H)-yl)tetrahydrofuran-2-yl)methyl isobutyrate (cas: 2492423-29-5Quality Control of ((2R,3S,4R,5R)-3,4-Dihydroxy-5-((Z)-4-(hydroxyimino)-2-oxo-3,4-dihydropyrimidin-1(2H)-yl)tetrahydrofuran-2-yl)methyl isobutyrate).

Tetrahydrofuran and dihydrofuran form the basic structural unit of many naturally occurring scaffolds like gambieric acid A and ciguatoxin, goniocin, and some biologically active molecules. THF can also be synthesized by catalytic hydrogenation of furan. This allows certain sugars to be converted to THF via acid-catalyzed digestion to furfural and decarbonylation to furan, although this method is not widely practiced. THF is thus derivable from renewable resources.Quality Control of ((2R,3S,4R,5R)-3,4-Dihydroxy-5-((Z)-4-(hydroxyimino)-2-oxo-3,4-dihydropyrimidin-1(2H)-yl)tetrahydrofuran-2-yl)methyl isobutyrate

Haspin-dependent and independent effects of the kinase inhibitor 5-Iodotubercidin on self-renewal and differentiation was written by Karanika, Eleftheria;Soupsana, Katerina;Christogianni, Anastasia;Stellas, Dimitris;Klinakis, Apostolos;Politou, Anastasia S.;Georgatos, Spyros. And the article was included in Scientific Reports in 2020.Product Details of 24386-93-4 The following contents are mentioned in the article:

The kinase Haspin phosphorylates histone H3 at threonine-3 (H3T3ph), creating a docking site for the Chromosomal Passenger Complex (CPC). CPC plays a pivotal role in preventing chromosome misalignment. Here, we have examined the effects of 5-Iodotubercidin (5-ITu), a commonly used Haspin inhibitor, on self-renewal and differentiation of mouse embryonic stem cells (ESCs). Treatment with low concentrations of 5-ITu eliminates the H3T3ph mark during mitosis, but does not affect the mode or the outcome of self-renewal divisions. Interestingly, 5-ITu causes sustained accumulation of p53, increases markedly the expression of histone genes and results in reversible upregulation of the pluripotency factor Klf4. However, the properties of 5-ITu treated cells are distinct from those observed in Haspin-knockout cells generated by CRISPR/Cas9 genome editing, suggesting “off-target” effects. Continuous exposure to 5-ITu allows modest expansion of the ESC population and growth of embryoid bodies, but release from the drug after an initial treatment aborts embryoid body or teratoma formation. The data reveal an unusual robustness of ESCs against mitotic perturbants and suggest that the lack of H3T3ph and the “off-target” effects of 5-ITu can be partially compensated by changes in expression program or accumulation of suppressor mutations. This study involved multiple reactions and reactants, such as (2R,3R,4S,5R)-2-(4-Amino-5-iodo-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-5-(hydroxymethyl)tetrahydrofuran-3,4-diol (cas: 24386-93-4Product Details of 24386-93-4).

Fullerene Derivatives for Drug Delivery against COVID-19: A Molecular Dynamics Investigation of Dendro[60]fullerene as Nanocarrier of Molnupiravir was written by Giannopoulos, Georgios I.. And the article was included in Nanomaterials in 2022.Application of 2492423-29-5 The following contents are mentioned in the article:

In this paper, a theor. investigation is made regarding the possibility of using a water-soluble derivative of C60 as a drug delivery agent for treating Coronavirus disease 2019 (COVID-19). Molnupiravir is chosen as the transporting pharmaceutical compound since it has already proved to be very helpful in saving lives in case of hospitalization. According to the proposed formulation, a carboxyfullerene known as dendro[60]fullerene is externally connected with two molnupiravir mols. Two properly formed nitrogen single bonds (N-N) are used as linkers between the dendro[60]fullerene and the two molnupiravir mols. to create the final form of the C60 derivate/molnupiravir conjugate. The energetics of the developed mol. system and its interaction with water and n-octanol are extensively studied via classical mol. dynamics (MD) using the COMPASS II force field. To study the interactions with water and n-octanol, an appropriate periodic amorphous unit cell is created that contains a single C60 derivative/molnupiravir system surrounded by numerous solvent mols. and simulated via MD in room conditions. In addition, the corresponding solvation-free energies of the investigated drug delivery system are computed and set in contrast with the corresponding properties of the water-soluble dendro[60]fullerene, to test its solubility capabilities. This study involved multiple reactions and reactants, such as ((2R,3S,4R,5R)-3,4-Dihydroxy-5-((Z)-4-(hydroxyimino)-2-oxo-3,4-dihydropyrimidin-1(2H)-yl)tetrahydrofuran-2-yl)methyl isobutyrate (cas: 2492423-29-5Application of 2492423-29-5).

Molecular pharmacology of adipocyte-secreted autotaxin was written by Moulharat, Natacha;Fould, Benjamin;Giganti, Adeline;Boutin, Jean A.;Ferry, Gilles. And the article was included in Chemico-Biological Interactions in 2008.Formula: C11H13IN4O4 The following contents are mentioned in the article:

Autotaxin is a type II ecto-nucleotide pyrophosphate phosphodiesterase enzyme. It has been recently discovered that autotaxin also catalyzes a lyso-phospholipase D activity. This enzyme probably provides most of the extracellular lyso-phosphatidic acid from lysophosphatidylcholine. There is almost no pharmacol. tools available to study autotaxin. Indeed, all the reported inhibitors, thus far, are uneasy-to-use, lyso-phosphatidic acid derivatives Initially, autotaxin was recognized as a phosphodiesterase (NPP2) [Bollen et al., Curr. Rev. Biochem. Biol. 35 (2000) 393-432], based on sequence similarity and enzymic capability of autotaxin to catalyze ecto-nucleotidase activity. Phosphodiesterase forms a large family of enzymes characterized by a large number of chem. diverse inhibitors. None of them have been tested on autotaxin activity. For this reason, we screened those reported inhibitors, as well as a series of compounds, mostly kinase inhibitor-oriented, on autotaxin activity. Only two compounds of the various phosphodiesterase inhibitors (calmidazolium and vinpocetine) were potent enough to inhibit autotaxin catalytic activity. From the kinase inhibitor library, we found damnacanthal and hypericin, inhibiting phosphodiesterase activity in the 100-μM range, comparable to most of other available phospholipid-like inhibitors.

Overexpression of adenosine kinase in epileptic hippocampus contributes to epileptogenesis was written by Gouder, Nicolette;Scheurer, Louis;Fritschy, Jean-Marc;Boison, Detlev. And the article was included in Journal of Neuroscience in 2004.Reference of 24386-93-4 The following contents are mentioned in the article:

Endogenous adenosine in the brain is thought to prevent the development and spread of seizures via a tonic anticonvulsant effect. Brain levels of adenosine are primarily regulated by the activity of adenosine kinase. To establish a link between adenosine kinase expression and seizure activity, the authors analyzed the expression of adenosine kinase in the brain of control mice and in a kainic acid-induced mouse model of mesial temporal lobe epilepsy. Immunohistochem. anal. of brain sections of control mice revealed intense staining for adenosine kinase, mainly in astrocytes, which were more or less evenly distributed throughout the brain, as well as in some neurons, particularly in olfactory bulb, striatum, and brainstem. In contrast, hippocampi lesioned by a unilateral kainic acid injection displayed profound astrogliosis and therefore a significant increase in adenosine kinase immunoreactivity accompanied by a corresponding increase of enzyme activity, which paralleled chronic recurrent seizure activity in this brain region. Accordingly, seizures and interictal spikes were suppressed by the injection of a low dose of the adenosine kinase inhibitor 5-iodotubercidin. We conclude that overexpression of adenosine kinase in discrete parts of the epileptic hippocampus may contribute to the development and progression of seizure activity. This study involved multiple reactions and reactants, such as (2R,3R,4S,5R)-2-(4-Amino-5-iodo-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-5-(hydroxymethyl)tetrahydrofuran-3,4-diol (cas: 24386-93-4Reference of 24386-93-4).

Activating mutations in KIT/PDGFRA receptor tyrosine kinases drive gastrointestinal stromal tumors (GIST). KIT/PDGFRA inhibitors, such as imatinib do not evoke an effective cytocidal response, leaving room for quiescence and development of multiple secondary resistance mutations. As the majority of the secondary resistance clones activate PI3K and MAPK pathways, we investigated whether combined targeting of KIT/PI3K/MAPK (KPM) pathways overcomes drug resistance and quiescence in GIST cells. We monitored the proliferation of imatinib-sensitive and-resistant GIST cell lines after treating them with various combinations of drugs to inhibit KPM pathways. Cytocidal response was evaluated through proliferation, apoptosis and colony outgrowth assays. Combined inhibition of KPM signaling pathways using a KPM inhibitor cocktail decreased the survival of drug-resistant GIST cells and dramatically reduced their proliferation. Downstream pathway anal. showed that the residual PI3K/MAPK signaling observed after KIT inhibitor treatment plays a role in mediating quiescence and drug resistance. The KPM inhibitor cocktail with sunitinib or regorafenib effectively induced apoptosis and prevented colony outgrowth after long-term drug removal, suggesting that it can be used as an effective strategy against quiescence and drug resistance in metastatic GIST.

Coronavirus disease 2019 (COVID-19) is a newly emerged infectious disease caused by a novel coronavirus, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The rapid global emergence of SARS-CoV-2 highlights the importance and urgency for potential drugs to control the pandemic. The functional importance of RNA-dependent RNA polymerase (RdRp) in the viral life cycle, combined with structural conservation and absence of closely related homologs in humans, makes it an attractive target for designing antiviral drugs. Nucleos(t)ide analogs (NAs) are still the most promising broad-spectrum class of viral RdRp inhibitors. In this study, using our previously developed cell-based SARS-CoV-2 RdRp report system, the author screened 134 compounds in the Selleckchems. NAs library. Four candidate compounds, Fludarabine Phosphate, Fludarabine, 6-Thio-20- Deoxyguanosine (6-Thio-dG), and 5-Iodotubercidin, exhibit remarkable potency in inhibiting SARS-CoV-2 RdRp. Among these four compounds, 5-Iodotubercidin exhibited the strongest inhibition upon SARS-CoV-2 RdRp, and was resistant to viral exoribonuclease activity, thus presenting the best antiviral activity against coronavirus from a different genus. Further study showed that the RdRp inhibitory activity of 5-Iodotubercidin is closely related to its capacity to inhibit adenosine kinase (ADK). This study involved multiple reactions and reactants, such as (2R,3R,4S,5R)-2-(4-Amino-5-iodo-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-5-(hydroxymethyl)tetrahydrofuran-3,4-diol (cas: 24386-93-4SDS of cas: 24386-93-4).

A review. Oral therapies for the early treatment of COVID-19 may prevent disease progression and health system overcrowding. A new oral therapeutic named molnupiravir has been promoted as providing an approx. 50% reduction in death or the need for hospitalization. The clin. trial evaluating this drug was stopped early at the recommendation of the Data Safety and Monitoring Board after approx. 50% of the sample had been recruited. At the point of discontinuing the trial, approx. 90% of the planned sample had been recruited and had available follow-up data accessible. We discuss issues about the study conduct, anal., and interpretation, including (1) the authors and sponsors presented the interim anal. as the primary anal.; (2) communication between sponsors and the Data Safety and Monitoring Board was insufficient; (3) the treatment effects reverse when examining only the post-interim anal. population, and are substantially attenuated when examining the full data; (4) the choice of primary anal. is incorrect; (5) anal. of lost-to-follow-up patients favors the study drug; and (6) other known molnupiravir trials were not presented in the primary study findings. As a result of methodol. and statistical concerns, it seems that external trials, sep. from those supported by the sponsoring company, are required to determine the utility of this drug. This study involved multiple reactions and reactants, such as ((2R,3S,4R,5R)-3,4-Dihydroxy-5-((Z)-4-(hydroxyimino)-2-oxo-3,4-dihydropyrimidin-1(2H)-yl)tetrahydrofuran-2-yl)methyl isobutyrate (cas: 2492423-29-5Recommanded Product: ((2R,3S,4R,5R)-3,4-Dihydroxy-5-((Z)-4-(hydroxyimino)-2-oxo-3,4-dihydropyrimidin-1(2H)-yl)tetrahydrofuran-2-yl)methyl isobutyrate).
