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...
متن کاملSynthesis 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...
متن کاملThe inhibitory action of kohamaic acid A derivatives on mammalian DNA polymerase beta.
We previously isolated a novel natural product, designated kohamaic acid A (KA-A, compound 1), as an inhibitor of the first cleavage of fertilized sea urchin eggs, and found that this compound could selectively inhibit the activities of mammalian DNA polymerases (pols). In this paper, we investigated the structure and bioactivity of KA-A and its chemically synthesized 11 derivatives (i.e., comp...
متن کاملPharmacological 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...
متن کاملSuppressive effects of glycyrrhetinic acid derivatives on tachykinin receptor activation and hyperalgesia.
Glycyrrhetinic acid (GA), an aglycone of glycyrrhizin, isolated from the licorice root (Glycyrrhizia), and its semi-synthetic derivatives have a wide range of pharmacological effects. To investigate whether GA derivatives may be used as a new class of analgesics, we examined the effects of these compounds on human tachykinin receptors expressed in CHO-K1 cells. Among the GA derivatives examined...
