Liquiritigenin, isoliquiritigenin rich extract of glycyrrhiza glabra roots attenuates inflammation in macrophages and collagen-induced arthritis in rats.

Liquiritigenin (LTG) and its bioprecursor isoliquiritigenin(ISL), the main bioactives from roots of Glycyrrhiza genus are progressively documented as a potential pharmacological agent for the management of chronic diseases. The aim of this study was to evaluate the pharmacological potential of liquiritigenin, isoliquiritigenin rich extract of Glycyrrhiza glabra roots (IVT-21) against the production of pro-inflammatory cytokines from activated macrophages as well as further validated the efficacy in collagen-induced arthritis model in rats. We also performed the safety profile of IVT-21 using standard in-vitro and in-vivo assays.

Effect of liquiritigenin on chloroquine accumulation in digestive vacuole leading to apoptosis-like death of chloroquine-resistant P. falciparum.

Background: Malaria remains one of the major health concerns, especially in tropical countries. Although drugs such as artemisinin-based combinations are efficient for treating Plasmodium falciparum, the growing threat from multi-drug resistance has become a major challenge. Thus, there is a constant need to identify and validate new combinations to sustain current disease control strategies to overcome the challenge of drug resistance in the malaria parasites.

Synthesis, molecular modelling studies of indolyl chalcone derivatives and their antimalarial activity evaluation.

Twenty one chalcone derivatives were synthesized using Claisen-Schmidt condensation, their antimalarial activity against was determined and quantitative structure-activity relationship (QSAR) was developed. Condensation of substituted acetophenones with various aromatic aldehydes at room temperature gave chalcones in 75-96% yield. Chalcones are secondary metabolites of terrestrial plants, precursors for the biosynthesis of flavonoids and exhibit various biological activities.

antiproliferative activity of glabridin derivatives and their target identification.

Novel Mannich base derivatives of glabridin were synthesized and their antiproliferative activity were performed along with our previously reported glabridin-chalcone hybrids molecules (GCHMs) against various human cell lines MDA-MB-231 (breast adenocarcinoma), HEK-293 (embryonic kidney cell line), K562 (leukemia), MCF-7 (breast adenocarcinoma), HeLa (cervix adenocarcinoma), HepG2 (hepatocellular carcinoma) and WRL-68 (hepatic carcinoma). The result showed that the glabridin significantly reduced cell proliferation with IC ranges from 3.67 to 58.
