BackgroundPtycholobium is a genus related to Tephrosia which comprises only three species. Compared to Tephrosia, which has been phytochemically and pharmacologically studied, Ptycholobium species have only few or no reports on their chemical constituents. Moreover, no studies on the cytotoxic activities of its secondary metabolites have been previously documented.ResultsFrom the non polar fractions of the roots bark of Ptycholobium contortum (syn Tephrosia contorta), two new pterocarpans… Expand
Synthesis of Novel Stilbene–Coumarin Derivatives and Antifungal Screening of Monotes kerstingii-Specialized Metabolites Against Fusarium oxysporum
Fusarium is one of the most toxigenic phytopathogens causing diseases and reduced agricultural productivity worldwide. Current chemical fungicides exhibit toxicity against non-target organisms,Expand
Cytotoxicity of seputhecarpan D, thonningiol and 12 other phytochemicals from African flora towards human carcinoma cells
TLDR
Compounds 9 and 13 are good cytotoxic phytochemicals that should be explored more in future to develop a cytot toxic drug to fight human carcinoma. Expand
Cytotoxicity of epunctanone and four other phytochemicals isolated from the medicinal plants Garcinia epunctata and Ptycholobium contortum towards multi-factorial drug resistant cancer cells.

TLDR
Compounds 1-5 are valuable cytotoxic compounds that could be used to combat MDR cancer cells and Benzophenoe 5 is the most active molecule and deserve more investigations to develop new anticancer drugs. Expand

A Review on the Phytochemistry and Pharmacology of Genus Tephrosia
TLDR
This review includes the chemical studies on different species mainly the isolation and identification of flavonoids, rotenoids and study of activity of some isolated compounds and also includes diffe-rent pharmacological activities like antioxidant, antimicrobial, anticancer, antiplas-modial, anti-inflammatory, larvicidal and toxicity studies of extracts and fractions.

The biosynthesis of quinones from p-hydroxybenzoic acid in Euglena gracilis var. bacillaris☆
TLDR
Etiolated cultures of E. gracilis readily incorporated p -[U- 14 C]hydroxybenzoic acid into ubiquinone-9 and the evidence suggests that the ubiquin one-9 was then metabolized to rhodoquinone- 9, suggesting that this compound was on the biosynthetic pathway of plastidic benzoquinones. Expand

TLDR
The studied plants are potential cytotoxic drugs that deserve more detailed exploration in the future, to develop novel anticancer drugs against sensitive and otherwise drug-resistant phenotypes. Expand
