The insertion of conventional diazocompounds into indoles are still limited by the custom carbene precursors, catalysts and manipulation of the products required. Herein, we address these shortcomings with a redox-active carbene precursor (NHPI-DA).
A new series of thiazole nortopsentin analogues was conveniently synthesized with fair overall yields. The antiproliferative activity of the new derivatives was tested against different human tumor cell lines of the NCI full panel. Four of them showed good antitumoractivity with GI50 values from micro to nanomolar level. The mechanism of the antiproliferative effect of these derivatives, was pro-apoptotic

Sulfonamide heterocycles, specifically 3-acylindoles, undergo a deprotection/alkylation sequence in the presence of an appropriate alcohol when cesium carbonate or potassium carbonate and a phase-transfer catalyst are utilized. The outcome of the one-pot protocol was found to be significantly dependent on both the alcohol and sulfonamide heterocycle employed. Strictly anhydrous conditions are not necessary

Disclosed herein are rhodanine derivatives, a method for the preparation thereof, and a pharmaceutical composition containing the same. The rhodanine derivatives have inhibitory activity against protein phosphatases (PPase) such as PTP1B, Prl-3, LAR, CD45, Cdc25A, Cdc25B, Cdc25C, Yop, PP1 and VHR, and can be applied for the prevention and treatment of PPase-caused diseases, including autoimmune diseases, diabetes, impaired glucose intolerance, insulin resistance, obesity, cancers, etc. when the inhibitory activity thereof is modulated.
