In this study, 22 new betulinic acid (BA) derivatives were synthesized and tested for their inhibition of the chymotrypsin-like activity of 20S proteasome. From the SAR study, we concluded that the C-3 and C-30 positions are the pharmacophores for increasing the proteasome inhibition effects, and larger lipophilic or aromatic side chains are favored at these positions. Among the BA derivatives tested, compounds 13, 20, and 21 showed the best proteasome inhibition activity with IC50 values of 1.42, 1.56, and 1.80 muM, respectively, which are three to fourfold more potent than the proteasome inhibition controls LLM-F and lactacystin.

Cryptosporidium inosine 5?-monophosphate dehydrogenase (CpIMPDH) has emerged as a therapeutic target for treating Cryptosporidium parasites because it catalyzes a critical step in guanine nucleotide biosynthesis. A 4-oxo-[1]benzopyrano[4,3-c]pyrazole derivative was identified as a moderately potent (IC50 = 1.5 muM) inhibitor of CpIMPDH. We report a SAR study for this compound series resulting in 8k (IC50 = 20 ± 4 nM). In addition, an X-ray crystal structure of CpIMPDH·IMP·8k is also presented.

Fatty acid biosynthesis is essential for bacterial survival. ss-Ketoacyl-acyl carrier protein (ACP) synthase III (FabH), is a particularly attractive antibacterial target, since it is central to the initiation of fatty acid biosynthesis. Three series of 21 cinnamaldehyde acylhydrazone derivatives, A3-9, B3-9, and C3-9, were synthesized and evaluated for FabH-inhibitory activity. Compound B6 showed the most potent biological activity against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, and Bacillus subtilis (minimum inhibitory concentrations (MICs) values: 1.56-3.13mug/mL) and was comparable with the positive control. Docking simulation by positioning compound B6 in the FabH structure active site was performed to explore the possible binding model.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms.In my other articles, you can also check out more blogs about 261767-10-6Reference of 261767-10-6.

Chemistry involves the study of all things chemical – chemical processes, chemical compositions and chemical manipulation – in order to better understand the way in which materials are structured, how they change and how they react in certain situations. Reference of 22013-33-8

Described herein is a dual chelation-assisted RhCl3-catalyzed oxidative C-H/C-H cross-coupling reaction of aniline derivatives. The highlight of this methodology is the chemo- and regioselective cross-coupling between electronically similar substrates, which represents a highly challenging task in oxidative Ar-H/Ar-H cross-coupling reactions. Furthermore, this Cp?-free catalytic reaction tolerates a range of functional groups and requires only a low molar ratio of coupling partners. These features expedite the synthesis of unsymmetrical 2,2?-diaminobiaryls.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Reference of 22013-33-8, you can also check out more blogs about22013-33-8
