A comprehensive view on 4-methyl-2-quinazolinamine, a new microbial alkaloid from Streptomyces of TCM plant origin.

5 Aug 2009 In the course of our chemical and biological screening program for yet unidentified microbial metabolites, we selected plants of Traditional Chinese Medicine (TCM) as habitats for talented Streptomycetes producer strains for the first time. Liquid ... Read more...

Effect of abiotic and biotic elicitors on growth and alkaloid accumulation of Lycoris chinensis seedlings.

29 Jun 2009 Three-month-old seedlings of Lycoris chinensis were treated with biotic and abiotic elicitors: yeast elicitor (YE), methyl jasmonate (MJ), salicylic acid (SA), and sodium nitroprusside as NO donator (NO). We have shown that the addition of MJ and NO ... Read more...

Highly efficient and concise synthesis of both antipodes of SB204900, clausenamide, neoclausenamide, homoclausenamide and zeta-clausenamide. Implication of biosynthetic pathways of Clausena alkaloids.

3 May 2009 The synthesis of both antipodes of N-methyl-N-[(Z)-styryl]-3-phenyloxirane-2-carboxamide (SB204900), clausenamide, neoclausenamide, homoclausenamide and zeta-clausenamide have been accomplished using (2S,3R)- and ... Read more...
