Chen, Deheng;Lu, Tian;Yan, Ziqin;Lu, Wenchao;Zhou, Feilong;Lyu, Xilin;Xu, Biling;Jiang, Hualiang;Chen, Kaixian;Luo, Cheng;Zhao, Yujun research published 《 Discovery, structural insight, and bioactivities of BY27 as a selective inhibitor of the second bromodomains of BET proteins》, the research content is summarized as follows. Recently, selective inhibition of BET BD2 is emerging as a promising strategy for drug discovery. Despite significant progress in this area, systematic studies of selective BET BD2 inhibitors are still few. In this study, we report the discovery of a potent and selective BET BD2 inhibitor BY27 (47). Our high resolution co-crystal structures of 47/BRD2 BD1 and BD2 showed that the triazole group of 47, water mols., H433 and N429 in BRD2 BD2 established a water-bridged H-bonding network, which is responsible for the observed selectivities. DNA microarray anal. of HepG2 cells treated with 47 or OTX015 demonstrated the transcriptome impact differences between a BET BD2 selective inhibitor and a pan BET inhibitor. In a MV4-11 mouse xenograft model, 47 caused 67% of tumor growth inhibition and was less toxic than a pan BET inhibitor 1 at high doses. We conclude that the improved safety profile of selective BET BD2 inhibitors warrant future studies in BET associated diseases.

Abdelsamie, Ahmed S.;Salah, Mohamed;Siebenbuerger, Lorenz;Hamed, Mostafa M.;Boerger, Carsten;van Koppen, Chris J.;Frotscher, Martin;Hartmann, Rolf W. research published 《 Development of potential preclinical candidates with promising in vitro ADME profile for the inhibition of type 1 and type 2 17β-Hydroxysteroid dehydrogenases: Design, synthesis, and biological evaluation》, the research content is summarized as follows. Estrogens are the major female sex steroid hormones, estradiol (E2) being the most potent form in humans. Disturbing the balance between E2 and its weakly active oxidized form estrone (E1) leads to diverse types of estrogen-dependent diseases such as endometriosis or osteoporosis. 17β-Hydroxysteroid dehydrogenase type 1 (17β-HSD1) catalyzes the biosynthesis of E2 by reduction of E1 while the type 2 enzyme catalyzes the reverse reaction. Thus, 17β-HSD1 and 17β-HSD2 are attractive targets for treatment of estrogen-dependent diseases. Recently, we reported the first proof-of-principle study of a 17β-HSD2 inhibitor in a bone fracture mouse model, using s.c. administration. In the present study, our aim was to improve the in vitro ADME profile of the most potent 17β-HSD1 and 17β-HSD2 inhibitors described so far. The optimized compounds show strong and selective inhibition of both the human enzymes and their murine orthologs. In addition, they display good metabolic stability in human liver microsomes (S9 fraction), low in vitro cytotoxicity as well as better aqueous solubility and physicochem. properties compared to the lead compounds These achievements make the compounds eligible for testing in preclin. in vivo animal model studies on the effects of inhibition of 17β-HSD1 and 17β-HSD2.

Zhu, Shuangfei;Yang, Wei;Gan, Qiang;Feng, Changgen research published 《 Initial Steps and Thermochemistry of Unimolecular Decomposition of Oxadiazole Energetic Materials: Quantum Chemistry Modeling》, the research content is summarized as follows. In order to resolve the existing discrepancies in the mechanism and key intermediates of oxadiazole thermolysis, the initial decomposition pathways of oxadiazoles have been studied comprehensively using the M062X method for optimization and CBS-QB3 and DLPNO-CCSD(T) methods for energies. The transformation from the furoxan ring to nitro group was suggested as a potential decay channel of furoxan compounds Results of thermochem. calculations showed that the preferred decomposition reaction of oxadiazoles is the ring-opening through the cleavage of the O-C or O-N bond. The introduction of the nitro group has little effect on the preferential path of oxadiazole thermal decomposition, but a great impact on the energy barrier. The lowest energy barrier and bond dissociation energy of NO₂ loss of azoles were comprehensively studied based on the quantum chem. calculations The initial decay steps of 3,4-dinitrofurazanfuroxan and benzotrifuroxan were also studied to give insights into the mechanism of primary stages of thermal decomposition of oxadiazoles.

CDK8 regulates transcription either by phosphorylation of transcription factors or, as part of a four-subunit kinase module, through a reversible association of the kinase module with the Mediator complex, a highly conserved transcriptional coactivator. Deregulation of CDK8 has been found in various types of human cancer, while the role of CDK8 in suppressing anti-cancer response of natural killer cells is being understood. Currently, CDK8-targeting cancer drugs are highly sought-after. Herein authors detail the discovery of a series of novel pyridine-derived CDK8 inhibitors. Medicinal chem. optimization gave rise to I (AU1-100), a potent CDK8 inhibitor with oral bioavailability. The compound inhibited the proliferation of MV4-11 acute myeloid leukemia cells with the kinase activity of cellular CDK8 dampened. No systemic toxicol. was observed in the mice treated with I. These results warrant further pre-clin. studies of I as an anti-cancer agent.

Hou, Shaohua;Yang, Xiping;Yang, Yuejing;Tong, Yu;Chen, Quanwei;Wan, Boheng;Wei, Ran;Lu, Tao;Chen, Yadong;Hu, Qinghua research published 《 Design, synthesis and biological evaluation of 1H-indazole derivatives as novel ASK1 inhibitors》, the research content is summarized as follows. A series of novel ASK1 inhibitors, e.g., I and II with 1H-indazole scaffold were designed, synthesized and evaluated for their ASK1 kinase activity and AP1-HEK293 cell inhibitory effect. Systematic structure-activity relationship (SAR) efforts led to the discovery of promising compound II, which showed excellent in vitro ASK1 kinase activity and potent inhibitory effects on ASK1 in AP1-HEK293 cells. In a tumor necrosis factor-α (TNF-α)-induced HT-29 intestinal epithelial cell model, compound II exhibited a significantly protective effect on cell viability comparable to that of GS-4997; moreover, compound II exhibited no obvious cytotoxicity against HT-29 cells at concentrations up to 25μM. Mechanistic research demonstrated that compound II suppressed phosphorylation in the ASK1-p38/JNK signaling pathway in HT-29 cells and regulated the expression levels of apoptosis-related proteins. Altogether, these results showed that compound II may serve as a potential candidate compound for the treatment of inflammatory bowel disease (IBD).
