15 صفحه اولIsolation and structure determination of a novel phosphatidylinositol turnover inhibitor, piericidin B1 N-oxide.
Sir: Piericidins are insecticidal compounds isolated from mycelia of Streptomyces mobaraensis1^ and Streptomyces pactum3'4K They are toxic to several species of insects, aphids, and mites. Piericidin A has been shown to block electron transport between NADHdehydrogenase and coenzyme Q5). The structures of the piericidin group have been elucidated. Members of this group are piericidins An, Bn, C...
متن کاملNew piericidin glucosides, glucopiericidins A and B.
The new piericidin group antibiotics, glucopiericidins A and B were isolated from the culture broth of Streptomyces pactum S48727 (FERM P-8117) as co-metabolite of piericidin A1. The structures of glucopiericidins A and B were determined as piericidin A1, 10-O-beta-D-glucoside and piericidin A1, 3'-O-D-glucoside on the basis of their spectral and chemical properties, respectively. Glucopiericid...
متن کاملA QUANTUM CHEMICAL STUDY OF STRUCTURE -ACTIVITY RELATIONSHIPS OF DIHYDROPYRIDINE CALCIUM ANTAGONISTS
Quantum chemical (MNDo)caleulations have beenused toelucidate the molecular properties and structure - activity relationships of dihydropyridine (DHP) type calcium antagonists. There is a good corielation between the net atomic charges on various atoms of the 4 - phenyl ring of dihydropyridines and pharmacological activity. .Also, activity decreases with increasing free rotation of the phen...
متن کاملProgress in HIV-1 integrase inhibitors: A review of their chemical structure diversity
HIV-1 integrase (IN) enzyme, one of the three main enzymes of HIV-1, catalyzed the insertion of the viral DNA into the genome of host cells. Because of the lack of its homologue in human cells and its essential role in HIV-1 replication, IN inhibition represents an attractive therapeutic target for HIV-1 treatment. Since identification of IN as a promising therapeutic target, a major progress h...
