It was found that a class of sulfolipids known as sulfo-quinovosyl-acyl-glycerols (SQAGs) from ferns and algae are potent inhibitors of eukaryotic DNA polymerase alpha and beta and effective anti-neoplastic agents. In developing a procedure for the chemical synthesis of sulfolipids, many derivatives

Two new saponins named avicins D (1) and G (2) were isolated from the seed pods of the desert legume plant Acacia victoriae. The structures, elucidated by 1D and 2D NMR studies and by chemical means, were characterized as acacic acid-bearing oligosaccharides at C-3 and C-28 with a side chain linked

Glycosides of arylnaphthalene lignans having axial chirality were isolated from Acanthus mollis. Owing to the axial chirality, their structure, including absolute configuration, was determined by means of extensive spectroscopic data such as UV, IR, MS, 1D and 2D NMR spectra, and computational

We reported previously that sulfolipids in the sulfoquinovosylacylglycerol class from a fern and an alga are potent inhibitors of DNA polymerase alpha and beta and potent anti-neoplastic agents. In developing a procedure for chemical synthesis of sulfolipids, we synthesized many derivatives and

Anticancer agents target various subcellular components and trigger apoptosis in chemosensitive cells. We have recently reported the tumor cell growth inhibitory properties of a mixture of triterpenoid saponins obtained from an Australian desert tree (Leguminosae) Acacia victoriae (Bentham). Here we

We reported previously that sulfo-glycolipids such as sulfoquinovosyl-diacylglycerol (SQDG) and sulfoquinovosyl-monoacylglycerol (SQMG) are potent inhibitors of DNA polymerase alpha and beta and antineoplastic agents. Then, we succeeded in synthesizing SQDG and SQMG chemically, including their

Holothuria polii (Delle Chiaje, 1823) (Holothuriidae) is a sea cucumber inhabiting Mediterranean Sea coast of Egypt. The bioactive compound of its tegument has antifungal, antibacterial and antiparasitic effects. The present study aims to elucidate the structure of the bioactive material of H. polii

A new nor-ceanothane-type triterpenoid, breynceanothanolic acid (1), and seven novel 4α-methyl sterols, fruticosides A-G (2-8), were obtained from the roots of Breynia fruticosa. The new compound structures were established by means of extensive spectroscopic and chemical methods. Compounds 7 and 8
