Chemopreventive activity of isoquinoline alkaloids from Corydalis plants

Eighteen isoquinoline alkaloids including protoberberines (1-12), benzophenanthridines (13-16) and an aporphine (17) isolated from plants of Corydalis species (Fumariaceae) were tested for inhibitory effects on Epstein-Barr virus early antigen activation induced by 12-O-tetradecanoylphorbol 13-acetate in Raji cells. In a primary screening test, all of the isoquinoline alkaloids showed inhibitory activity with the IC50 values being in the range of 140-410 mol ratio/32 pmol TPA. The data demonstrate that these isoquinoline alkaloids might be valuable as anti-tumor promoters.

Synthesis of tetracyclic dioxygenated isoquinolines and their cytotoxic activity

An efficient synthesis of new dioxygenated isoquinolines is reported. The novelty of this approach derives from its use of tricyclic-nitril (3) as a building block in a synthetic sequence of seven steps for the preparation of the tetracyclic isoquinoline (14) and its derivatives. The isoquinoline 16 was 10-fold more active against leukemia L-1210 than the corresponding tetrahydroisoquinoline 14. (C) 2008 Elsevier Ltd. All rights reserved.

Synthesis of Isoquinoline Alkaloids via Oxidative Amidation-Bischler-Napieralski Reaction

A straightforward synthesis of alpha-keto amides by coupling primary amines with aryl dibromoethanones under oxidative amidation conditions has been developed. The alpha-keto amides were then subjected to heterocyclodehydration reaction under Bischler-Napieralski conditions followed by aromatization with DBU provided 1-benzoyl isoquinolines in a two-stage process. Utilizing this methodology, isoquinoline alkaloids such as thalmicrinone, papavaraldine, and pulcheotine A were synthesized in excellent yields.

Whereas 1,3,10,10a-tetrahydro-5H-oxazolo[3,4-b]isoquinoline adopts an equilibrium in CDCl3 solution at 295 K in which the trans-fused conformation predominates, 1,5,6,10b-tetrahydro-3H-oxazolo[4,3-a] isoquinoline adopts the O-inside cis-fused conformation. This difference in conformational preference has been explained partly in terms of ring-fusion strain.
