A new laboratory method for isolating the glycosides stevioside and rebaudiosides A and C from leaves of Stevia rebaudiana was proposed. According to HPLC, the glycoside contents in plants grown in… (More)
A series of novel triphenylphosphonium (TPP) cations of the diterpenoid isosteviol (1, 16-oxo-ent-beyeran-19-oic acid) have been synthesized and evaluated in an in vivo phenotypic sea urchin embryo… (More)
Diesters based on isosteviol and dicarboxylic acids were synthesized and tested for antituberculous activity. Isosteviol and some of its derivatives exhibit appreciable tuberculostatic properties in… (More)
Mitochondria play a crucial role in the cell fate; in particular, reducing the accumulation of calcium in the mitochondrial matrix offers cardioprotection. This affect is achieved by a mild… (More)
Conjugates of betulinic, oleanolic, ursolic, and glycyrrhetic acids and several of their derivatives with the antituberculosis drug isoniazid and 3- and 4-pyridinecarboxaldehydes were synthesized.
Macrocycles with two or four ent-beyerane diterpenoid frameworks joined by ester spacers with various polymethylene chain lengths (n = 2, 6, 8) were synthesized for the first time from the… (More)
Novel phosphorylated derivatives of the diterpenoid isosteviol were synthesized and exhibited antituberculosis, antimicrobial, and anticancer activity.
The first derivatives containing two lupan backbones were synthesized by the interaction of betulonic acid chloride with diols (ethylene glycol and diethylene glycol) and monoethanolamine. A… (More)
Derivatives of the diterpenoid isosteviol (16-oxo-ent-beyeran-19-oic acid) with azine, hydrazone, and hydrazide moieties were synthesized. They exhibited high tuberculostatic activity in vitro… (More)
Previously unknown conjugates of the diterpenoid isosteviol 1 and 1-O-methyl-2,3-di-O-acetyl-β-Darabinofuranoside in which the terpenoid and carbohydrate molecules were linked through polymethylene… (More)
