Multidrug resistance is the expression of one or more efflux pumps, such as P-glycoprotein, and is a major obstacle in cancer therapy. The use of new potent and noncytotoxic efflux pump modulators, coadministered with antineoplastic agents, is an alternative approach for increasing the success rate

Tyrianthinic acids from Ipomoea tyrianthina and their antimycobacterial activity, cytotoxicity, and effects on the central nervous system.

Ingia / Ingia

Four new partially acylated tetrasaccharides of 11-hydroxyhexadecanoic acid (1-4) were isolated from a methanolic extract of Ipomoea tyrianthina. The structures of these compounds were elucidated by spectroscopic and chemical methods. The resin glycoside composition of I. tyrianthina varied with the

Ingia / Ingia

The methanol-soluble extract from the root of Ipomoea tyrianthina was studied in order to isolate compounds with activity on the central nervous system and vasorelaxant effects. Chromatographic methods were used to isolate and purify seven new glycolipids (2-8). The structures of compounds 1-8 were

Ingia / Ingia

Nine new lipo-oligosaccharides, batatosides H-P, were isolated from the tubers of Ipomoea batatas (Convolvulaceae). Spectral and chemical methods allowed to characterize them as tetra- or penta-saccharides that form a macrolactone with the aglycone, (11S)-hydroxyhexadecanoic acid (jalapinolic acid),

Ingia / Ingia

Three fatty acid glycosides, designated pescaprosides A, B, and E, have been isolated from Ipomoea pescaprae (family Convolvulaceae). Chemical studies on pescaproside E, the major product, led to its characterisation as a pentaglycoside of 11-hydroxyhexadecanoic acid. Its sugar chain was esterified
