The steroidal withanolide nr L-01. withaferin A ( Withania somnifera ) and the xanthone polyphenol mangiferin ( Mangifera indica ) hold much promise as potential novel cancer chemopreventive or therapeutic compounds. However, it is a great challenge to elucidate their polypharmacological anti-cancer mechanisms. To address this challenge, we apply bioinformatics methods to identify multiple targets of chemical agents through analysis of the gene expression profiles following in vitro /in vivo treatment.

Sw., Ocimum tenuiflorum , Persea americana , Sechium Collantes, Sancti Spiritus: CSF. J Pharm Pharmacogn Res 3(Suppl. 1): edule , Momordica charantia and Jatropha aethiopica . S2. Abstract nr L-02. Methods: Leaves aqueous extracts and its fractions were evaluated on protein tyrosine phosphatase 1B (PTP1B) and dipeptidyl peptidase-IV (DPPIV) enzymatic activities and the glucose uptake to identify candidates as phytopharmaceuticals in treating diabetes . In PTP1B assay (DiFMUP) was used as substrate and (TFMS) as standard inhibitor; in DPPIV assay (Gly-pro-AMC) was used as substrate and as standard inhibitor (P32/98); in both assays, the enzymatic activity inhibition was calculated by fluorescence using excitation wavelength of 360 nm and emission wavelength of 460 nm. Glucose uptake studies were performed on fully differentiated 3T3-L1 adipocyte using 2-deoxy-D-3H glucose and insulin as positive control, radioactivity into the cells was measured with a microplate scintillation counter. Results: The extracts from A. cominia , O. tenuiflorum and P. americana inhibited the enzymatic activity of PTP1B in a concentration dependent manner, resulting more actives the polar fractions from A. cominia and P americana. All the extracts and fractions showed inhibition of enzymatic activity of DPPIV, at higher concentrations. A. cominia inhibited enzymatic activity of this protease in an extract concentration dependent manner. A. cominia , O. tenuiflorum and P. americana extracts exhibited enhance of glucose uptake in 3T3-L1 adipocytes. Conclusions: The aqueous extracts from A. cominia , P. americana and O. tenuiflorum and some of its fractions could be promising antidiabetic candidates. Further A. cominia studies based on bio-guided estructure-activity assays of the aqueous extracts and fractions revealed quercitrin and mearnsetrin flavonoids as the key components in that activity. http://jppres.com/jppres J Pharm Pharmacogn Res (2015) 3(Suppl. 1):S 2 Proceedings of the 4th International Symposium on Pharmacology of Natural Products FAPRONATURA 2015 September 21st-25th, 2015; Topes de Collantes, Santi Spiritus, Cuba Cuban Society of Pharmacology Journal of Pharmacy & Pharmacognosy Research Volume 3, Supplement 1 (September) : S1 -S189 , 2015 L-03: NATURAL PRODUCTS: A KEY-POINT FOR THE CUBAN PROGRAM OF TRADITIONAL AND NATURAL MEDICINE Perdomo-Delgado J .
