Chemoreception: Tasting the sweet and the bitter

Our understanding of the molecular basis of taste transduction has lagged behind that of other senses, but now a signalling protein-the G protein alpha subunit gustducin-has been shown to be taste-tissue specific and essential for both bitter and sweet tastes.

Pharmacological activities of glycyrrhetinic acid derivatives: analgesic and anti-type IV allergic effects.

Glycyrrhetinic acid (Ia) and fourteen derivatives of glycyrrhetinic acid were examined to estimate the antinociceptive activity (tests on writhing and vascular permeability induced by 0.7% acetic acid) and anti-type IV allergic effects in mice. Among them, three dihemiphthalate compounds (IIf, IIIc, IVc) derived from, deoxoglycyrrhetol (IIa), showed strong inhibition of writhing and dye leakage...

Synthesis and Pro-Apoptotic Activity of Novel Glycyrrhetinic Acid Derivatives

Triterpenoids are used for medicinal purposes in many countries. Some, such as oleanolic and glycyrrhetinic acids, are known to be anti-inflammatory and anticarcinogenic. However, the biological activities of these naturally occurring molecules against their particular targets are weak, so the synthesis of new synthetic analogues with enhanced potency is needed. By combining modifications to bo...

Synthesis and Anticancer Activities of Glycyrrhetinic Acid Derivatives.

A total of forty novel glycyrrhetinic acid (GA) derivatives were designed and synthesized. The cytotoxic activity of the novel compounds was tested against two human breast cancer cell lines (MCF-7, MDA-MB-231) in vitro by the MTT method. The evaluation results revealed that, in comparison with GA, compound 42 shows the most promising anticancer activity (IC50 1.88 ± 0.20 and 1.37 ± 0.18 µM for...
