A new series of arachidonic acid derivatives were synthesized and evaluated as inhibitors of the endocannabinoiduptake. Most of them are able to inhibit anandamide uptake with IC(50) values in the low micromolar range (IC(50) = 0.8-24 microM). In general, the compounds had only weak effects upon CB(1), CB(2), and VR(1) receptors (K(i) > 1000-10000 nM). In addition, there was no obvious relationship

A complementary dual carbonyl activation strategy for the synthesis of polycyclic alkaloids has been developed. Successful applications include the synthesis of tetracyclic alkaloids harmalanine and harmalacinine, pentacyclic indoloquinolizidine alkaloid nortetoyobyrine, and octacyclic β-carboline alkaloid peganumine A. The latter synthesis features a protecting-group-free assembly and an asymmetric
已经开发出用于合成多环生物碱的互补双羰基活化策略。成功的应用包括四环生物碱骆驼蓬菌素和骆驼蓬菌素、五环吲哚喹啉西啶生物碱去甲代拜林和八环β-咔啉生物碱peganumine A的合成。后者的合成具有无保护基组装和不对称二磺酰亚胺催化环化的特点。此外,还实现了 hirsutine、deplancheine、10-desbromoarborescidine A 和 oxindole 生物碱钩藤碱和异钩藤碱的正式合成。最终完成了小檗碱生物碱ilicifoline B的简捷合成。

proven difficult, the judicious use of HuPhyrin ligand by tuning the bridgelength and other remote non-chiral elements allows for controlling both the degree and sense of asymmetric induction in a systematic manner. This effort leads to successful development of new Co(II)-based catalytic systems that are highly effective for enantiodivergent radical 1,5-C-H amination, producing both enantiomers of the

Skeletal diversity: The reactions of alkynoic acids (A, common type of substrates) with various scaffold‐building agents (B) under gold catalysis produce a series of multifunctional polyheterocyclic structures (see scheme). The approach enables the preparation of compound libraries with high skeletal diversity.
