  Non-insulin dependent diabetes mellitus is a multifactorial disease that links different metabolic routes: a point of convergence is the enzyme PTP-1B which turns off insulin and leptin receptors involved in glucose and lipid metabolism, respectively. Pentacyclic acid triterpenes such as oleanolic acid (OA) have proved to be excellent PTP-1B inhibitors, thus, the purpose of current work was to generate a series of derivatives that improve the pharmacological effect of OA. Our findings suggest that the presence of the carboxylic acid and/or its corresponding reduction product carbinol derivative (H-bond donor) in C-28 is required to maintain the inhibitory activity: moreover, this is further enhanced by ester or ether formation on C-3. The most active derivatives were cinnamoyl ester (6) and ethyl ether (10). Compound 6 showed potent in vitro inhibitory activity and significantly decrease of blood glucose levels on in vivo experiments. Meanwhile, 10 showed contrasting outcomes, since it was the compound with higher inhibitory activity and selectivity over PTP-1B and has improved interaction with site B, according with docking studies, the in vivo antidiabetic effect was similar to oleanolic acid. In conclusion, oleanolic acid derivatives have revealed an enhanced inhibitory effect over PTP-1B activity by increasing molecular interactions with either catalytic or allosteric sites and producing a hypoglycaemic effect on non insulin dependent diabetes mellitus rat model.

  Betulinic acid, oleanolic acid and ursolic acid have been modified at the C-3 position to cinnamate-based esters and in vitro antimycobacterial activity against Mycobacterium tuberculosis H(37)Ra has been determined. The results indicated that modification of the parent structures of betulinic acid, oleanolic acid and ursolic acid to the p-coumarate and, in the case of the latter two triterpenes, the ferulate
