excitingly, our studies of 5q in camptothecin (CCRF-CEM/C2) and mitoxantrone (HL-60/MX2) resistant cancer cells highlight its ability to selectively kill drug-resistant cells over parent cancer cells. 5q inhibits tumor cell growth through the induction of apoptosis, with detailed mechanism of its selectivity toward drug-resistant cancer cells under investigation. These results suggest that 5q is a promising

Two new N-heterocyclic carbene (NHC) ligands have been synthesized and employed in the transition metal-free asymmetric allylic alkylation (AAA) mediated by Grignardreagents and magnesium alanates. The employment of these ligands showed high yields and improved regio- and enantioselectivity in the formation of tertiary and quaternary stereocenters. Moreover, the low catalyst loading (up to 0.3 mol%)

N,N,O-Tridentate palladium(ii) complex 4a was found to be an efficient catalyst for the Suzuki cross-couplingreaction of aryl halides (iodo-, bromo- and chloro-), which afforded cross-coupling products in good to excellent yields.
N,N,O-三齿钯 (ii) 配合物 4a 被发现是芳基卤化物(碘-、溴-和氯-)的 Suzuki 交叉偶联反应的有效催化剂,可提供良好的交叉偶联产物优良的产量。
