Pharmacophore, similarity and ADMET screening of casein kinase 1 inhibitors in Alzheimer’s disease was written by Rodrigues, R. P.;Silva, C. H. T. P.. And the article was included in Current Bioactive Compounds in 2013.Name: (2R,3R,4S,5R)-2-(4-Amino-5-iodo-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-5-(hydroxymethyl)tetrahydrofuran-3,4-diol The following contents are mentioned in the article:

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder characterized by marked atrophy of cortex and loss of cortical and subcortical neurons. At least two Casein Kinase 1 isoforms have been implicated in the pathogenesis of AD. The ligand-based virtual screening (LBVS) technique uses the information of a set of actives, focusing on the activity of this group of mols. against the desired target. Generally, this type of technique is used when there is no information on the three dimensional structure of the target. However, the use of LBVS allied with three-dimensional information of the protein binding site provides a more accurate screening, since the information of the active site is taken into account during the anal. of results. 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: 24386-93-4Name: (2R,3R,4S,5R)-2-(4-Amino-5-iodo-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-5-(hydroxymethyl)tetrahydrofuran-3,4-diol).

Tetrahydrofuran (THF) is a Lewis base that bonds to a variety of Lewis acids such as I2, phenols, triethylaluminum and bis(hexafluoroacetylacetonato)copper(II). Commercial tetrahydrofuran contains substantial water that must be removed for sensitive operations, e.g. those involving organometallic compounds. Although tetrahydrofuran is traditionally dried by distillation from an aggressive desiccant, molecular sieves are superior.Name: (2R,3R,4S,5R)-2-(4-Amino-5-iodo-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-5-(hydroxymethyl)tetrahydrofuran-3,4-diol

The Covid-19 pandemic highlights the urgent need for cost-effective processes to rapidly manufacture antiviral drugs at scale. Here we report a concise biocatalytic process for Molnupiravir, a nucleoside analog recently approved as an orally available treatment for SARS-CoV-2. Key to the success of this process was the development of an efficient biocatalyst for the production of N-hydroxy-cytidine through evolutionary adaptation of the hydrolytic enzyme cytidine deaminase. This engineered biocatalyst performs >85 000 turnovers in less than 3 h, operates at 180 g/L substrate loading, and benefits from in situ crystallization of the N-hydroxy-cytidine product (85% yield), which can be converted to Molnupiravir by a selective 5′-acylation using Novozym 435.

The TOPol. Sub-Structural Mol. Design (TOPS-MODE) approach has been used to address the adenosine kinase inhibitory activity of pyrrolo[2,3-d]pyrimidine nucleoside analogs. A model capable of describing around 77% of the variance in exptl. activity of 32 analogs was developed on the basis of this approach. In contrast, out of nine different approaches, including the use of Constitutional, Topol., BCUT, 2D autocorrelations, geometrical, RDF, 3D Morse, WHIM, and GETAWAY descriptors none were able to explain more than 70% of the variance in the above-mentioned property with the same number of descriptors.

Development of a screening strategy for new modulators of T cell receptor signaling and T cell activation was written by Chen, Elijah W.;Brzostek, Joanna;Gascoigne, Nicholas R. J.;Rybakin, Vasily. And the article was included in Scientific Reports in 2018.Application of 24386-93-4 The following contents are mentioned in the article:

Activation of the T cell receptor (TCR) leads to the generation of a network of signaling events critical to the developmental decision making and activation of T cells. Various exptl. approaches continue to identify new signaling mols., adaptor proteins, and other regulators of TCR signaling. We propose a screening strategy for the identification of small mols. affecting TCR signaling based on the uncoupling of TCR stimulation from cellular responses in developing thymocytes. We demonstrate that this strategy successfully identifies inhibitors of kinases already shown to act downstream of TCR engagement, as well as new inhibitors. The proposed strategy is easily scalable for high throughput screening and will contribute to the identification of new druggable targets in T cell activation.

And the article was included in Bioconjugate Chemistry in 2015.Reference of 24386-93-4 The following contents are mentioned in the article:

During the past decade, the basophilic atypical kinase Haspin has emerged as a key player in mitosis responsible for phosphorylation of Thr3 residue of histone H3. Here, we report the construction of conjugates comprising an aromatic fragment targeted to the ATP-site of Haspin and a peptide mimicking the N-terminus of histone H3. The combination of effective solid phase synthesis procedures and a high throughput binding/displacement assay with fluorescence anisotropy readout afforded the development of inhibitors with remarkable subnanomolar affinity toward Haspin. The selectivity profiles of novel conjugates were established by affinity studies with a model basophilic kinase (catalytic subunit of cAMP-dependent protein kinase) and by a com. 1-point inhibition assay with 43 protein kinases.
