4-Chlorocolchicine derivatives bearing a thiourea side chain at the C-7 position as potent anticancer agents

A series of 4-substituted colchicine derivatives were synthesized and evaluated with an eye toward developing new anticancer agents. As a result, 4-chlorocolchicine derivatives bearing a thioureide side chain at the C-7 position were found to exhibit significant cytotoxicities to three human cancer cell lines (A549, HT-29, and HCT116). In particular, compound 26 having an ethylthioureide group at the C-7 had high antitumor activity in vivo and a broad effective dosage range. Furthermore, compound 58, which has a (5-methylpyrazol-3-yl)thioureide group at the C-7 side chain, exhibited strong cytotoxicity and desirable metabolic stability in vitro.

Discovery, synthesis, and biological evaluation of thiazoloquin(az)olin(on)es as potent CD38 inhibitors

A series of thiazoloquin(az)olinones were synthesized and found to have potent inhibitory activity against CD38. Several of these compounds were also shown to have good pharmacokinetic properties and demonstrated the ability to elevate NAD levels in plasma, liver, and muscle tissue. In particular, compound 78c was given to diet induced obese (DIO) C57Bl6 mice, elevating NAD > 5-fold in liver and >1.2-fold in muscle versus control animals at a 2 h time point. The compounds described herein possess the most potent CD38 inhibitory activity of any small molecules described in the literature to date. The inhibitors should allow for a more detailed assessment of how NAD elevation via CD38 inhibition affects physiology in NAD deficient states.

Rh-Catalyzed Construction of Quinolin-2(1H)-ones via C-H Bond Activation of Simple Anilines with CO and Alkynes

A novel and efficient Rh-catalyzed carbonylation and annulation of simple anilines with CO and alkynes through N-H and C-H bond activation for the direct synthesis of quinolin-2(1H)-ones has been developed. Simple anilines without preactivation, broad substrate scope with hetero/polycycles, and high-value products make this protocol very practical and attractive. A key rhodacycle complex was isolated and well-characterized.
