Recommanded Product: 17347-61-4, In chemical reaction engineering, simulations are useful for investigating and optimizing a particular reaction process or system.

A nickel-catalyzed alkylation of succinic and glutaric anhydrides with alkyl- and arylzinc reagents has been developed. A dramatic olefin effect has been investigated resulting in the identification of several styrene-based promoters which show pronounced enhancements in reaction rate. The substrate scope with respect to electrophilic and nucleophilic coupling partners has been examined and found to be remarkably broad, allowing for rapid introduction of molecular complexity through the use of functionalized coupling partners. Regioselective alkylation of an unsymmetrical succinic anhydride and a profound effect of pendent coordinating olefins on reaction rate suggest a mechanism involving discrete oxidative addition of the nickel complex into the cyclic anhydride followed by a transmetalation event.

Betulinic acid (BA), a pentacyclic triterpenoid, exhibits broad spectrum antiproliferative activity, but generally with only modest potency. To improve BA’s pharmacological properties, fluorine was introduced as a single atom at C-2, creating two diastereomers, or in a trifluoromethyl group at C-3. We evaluated the impact of these groups on antiproliferative activity against five human tumor cell lines. A racemic 2-F-BA (compound 6) showed significantly improved antiproliferative activity, while each diastereomer exhibited similar effects. We also demonstrated that 2-F-BA is a topoisomerase (Topo) I and IIalpha dual inhibitor in cell-based and cell-free assays. A hypothetical mode of binding to the Topo I-DNA suggested a difference between the hydrogen bonding of BA and 2-F-BA to DNA, which may account for the difference in bioactivity against Topo I.

The paper reports on the synthesis of a series of acyl derivatives of betulin and dihydroquinopimaric acid and the study of their antiviral activity against influenza A virus (H7N1), herpes simplex virus type 1 (HSV-1), ECHO 6, and HIV-1 in comparison with the activity of the previously obtained acylates and original terpenoids. It has been demonstrated that acylated betulin and betulinic acid show no advantage in inhibiting the reproduction of all the tested viruses compared with the betulic acid, while structural modifications at positions C3 and C28 of the triterpene core led to some changes in the spectrum of antiviral activity. Modification of dihydroquinopimaric acid at position C4 increased the activity of this compound against influenza virus A (H7N1).

The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 17347-61-4, 2,2-Dimethylsuccinicanhydride, introducing its new discovery.

Oleanolic acid (1) was identified as an anti-HIV principle from several plants, including Rosa woodsii (leaves), Prosopis glandulosa (leaves and twigs), Phoradendron juniperinum (whole plant), Syzygium clavifiorum (leaves), Hyptis capitata (whole plant), and Ternstromia gymnanthera (aerial part). It inhibited HIV-1 replication in acutely infected H9 cells with an EC50 value of 1.7 mug/mL, and inhibited H9 cell growth with an IC50 value of 21.8 mug/mL [therapeutic index (T. I.) 12.8]. Pomolic acid, isolated from R. woodsii and H. capitata, was also identified as an anti-HIV agent (EC50 1.4 mug/mL, T. I. 16.6). Although ursolic acid did show anti-HIV activity (EC50 2.0 mug/mL), it was slightly toxic (IC50 6.5 mug/mL, T. I. 3.3). A new triterpene (11) was also isolated from the CHCl3-soluble fraction of R. woodsii, though it showed no anti-HIV activity. The structure of 11 was determined to be 1beta-hydroxy-2-oxopomolic acid by spectral examination. Based on these results, we examined the anti-HIV activity of oleanolic acid- or pomolic acid-related triterpenes isolated from several plants. In addition, we previously demonstrated that derivatives of betulinic acid, isolated from the leaves of S. claviflorum as an anti-HIV principle, exhibited extremely potent anti-HIV activity. Accordingly, we prepared derivatives of oleanolic acid and evaluated their anti-HIV activity. Among the oleanolic acid derivatives, 18 demonstrated most potent anti-HIV activity, with an EC50 value of 0.0005 mug/mL and a T. I. value of 22 400.
