Design and Synthesis of a 2-Amino-pyridine Derivative as a Potent CDK8 Inhibitor for Anti-colorectal Cancer Therapy.

CDK8 is a transcriptional cyclin-dependent kinase and considered as a potential target in colon cancer therapeutics. Here, a novel selective CDK8 inhibitor was identified against colon cancer . Specifically, based on the structural information of the sorafenib-bound CDK8 structure, a series of novel 2-amino-pyridine derivatives were designed, synthesized, and evaluated.

Cathepsin C inhibitors as anti-inflammatory drug discovery: Challenges and opportunities.

Cathepsin C, an important lysosomal cysteine protease, mediates the maturation process of neutrophil serine proteases, and participates in the inflammation and immune regulation process associated with polymorphonuclear neutrophils. Therefore, cathepsin C is considered to be an attractive target for treating inflammatory diseases. With INS1007 (trade name: brensocatib) being granted a breakthrough drug designation by FDA for the treatment of Adult Non-cystic Fibrosis Bronchiectasis and Coronavirus Disease 2019, the development of cathepsin C inhibitor will attract attentions from medicinal chemists in the future soon.

Design, synthesis and anticancer activity of naphthoquinone derivatives.

Basis on molecular docking and pharmacophore analysis of naphthoquinone moiety, a total of 23 compounds were designed and synthesised. With the help of reverse targets searching, anti-cancer activity was preliminarily evaluated, most of them are effective against some tumour cells, especially compound : 1-(5,8-dihydroxy-1,4-dioxo-1,4-dihydronaphthalen-2-yl)-4-methylpent-3-en-1-yl-4-oxo-4-((4-phenoxyphenyl)amino) butanoate whose IC against SGC-7901 was 4.1 ± 2.

Binding patterns and structure-activity relationship of CDK8 inhibitors.

A major goal of medicinal chemists is to identify and validate novel and effective kinase targets for treatment of cancer. Recent studies have shown that cyclin-dependent kinase 8 (CDK8) is a target for treatment of colorectal, breast, melanoma, and prostate cancers. The crystal structure of CDK8 has been reported, and eutectic interactions have been identified for 24 compounds that target CDK8.

Novel naphthalene-enoates: Design and anticancer activity through regulation cell autophagy.

Eleven dihydroxy-2-(1-hydroxy-4-methylpent-3-enyl)naphthalene derivatives as anticancer agents through regulating cell autophagy were designed and synthesized. The anticancer activity results indicated that most compounds manifested obvious un-toxic effect on GES-1 and L-02 with IC from 0.58 to 1.

Direct C-H bond arylation of (benzo)oxazoles with aryl chlorides catalyzed by N-heterocyclic carbene-palladium(II)-1-methylimidazole complex.

The direct C-H bond arylation of (benzo)oxazoles with aryl chlorides was achieved catalyzed by a well-defined NHC-Pd(II)-Im complex. Under the optimal conditions, various aryl chlorides were successfully applied as the arylating reagents to achieve the 2-aryl (benzo)oxazoles in acceptable to high yields, providing a convenient and alternative method for the direct C-H bond arylation of (benzo)oxazoles and enriching the chemistry of the NHC-Pd(II) complex in organic synthesis.
