Biological properties of new acyl derivatives of tylosin.
The antibacterial activity of acyl derivatives of tylosin were examined in vitro and in vivo. The 4"-acyl group in the acylated tylosins enhanced the antibacterial activity and antimycoplasmal activity against some macrolide-resistant strains. The orally administered 3-acetyl-4" -isovaleryltylosin produced a higher blood level in mice and rabbits than tylosin and a good therapeutic effect on th...
متن کاملSynthesis and biological activities of turkesterone 11α-acyl derivatives
Turkesterone is a phytoecdysteroid possessing an 11alpha-hydroxyl group. It is an analogue of the insect steroid hormone 20-hydroxyecdysone. Previous ecdysteroid QSAR and molecular modelling studies predicted that the cavity of the ligand binding domain of the ecdysteroid receptor would possess space in the vicinity of C-11/C-12 of the ecdysteroid. We report the regioselective synthesis of a se...
متن کاملSynthesis and biological evaluation of some new N-fatty acyl derivatives of 4,5-dimethoxy tryptamine
The aim of this study is to synthesize and examine the in vitro anticancer, antioxidant and antimicrobial activities of N-fatty acyl derivatives of 4,5-dimethoxy tryptamine. A series of new N-fatty acyl derivatives of 4,5-dimethoxy tryptamine compounds derived from 2,3-dimethoxy benzaldehyde have been prepared. The synthesized compounds have been characterized and screened for anticancer, antio...

Seven new dammarane-type triterpenoid saponins, chikusetsusaponin FK1 (1), chikusetsusaponin FK2 (2), chikusetsusaponin FK3 (3), chikusetsusaponin FK4 (4), chikusetsusaponin FK5 (5), chikusetsusaponin FK6 (6), and chikusetsusaponin FK7 (7), and eleven known triterpenoid saponins, ginsenoside Rb3 (9), ginsenoside Rc (10), chikusetsusaponin VI (11), ginsenoside Re (12), ginsenoside Rg1 (13), pseu...
متن کامل[New coumarin derivatives with expected biological activity].
A number of novel 3-bromo-4-methyl-7-methoxy-8-amino substituted coumarins and 2-substituted 7-bromo-6-methyl-8H-pyrano-benzimidazoles, benzoxazoles and/or benzoxazine-8-ones were synthesized for the purpose of pharmacological evaluation. Some representative compounds showed antitumor activity in vitro on Ehrlich ascites carcinoma in the preliminary testing.
