ABSTRACT
Obesity-related metabolic disorders are increasing at an alarming rate worldwide. The FDA has approved many molecules for weight loss therapy; most of them act on the gut level by inhibiting lipid uptake or on the central nervous system by controlling appetite. Limitations and drawbacks have propelled the search for new pharmacophores exhibiting favourable metabolic alteration at adipocytes, and natural products have always been there to prove their worth. In our efforts, we have identified 16-hydroxy-ent-halima-5(10),13-dien-15,16-olide (PLH), a halimane diterpene isolated from Polyalthia longifolia, demonstrating anti-adipogenic and anti-dyslipidemic activity. It inhibited adipogenesis in 3T3-L1 preadipocyte and C3H10T1/2 mesenchymal stem cell lines. Furthermore, it decreased set of adipogenic markers at transcript and protein levels. Cell cycle studies indicated that PLH halts the mitotic clonal expansion. Mechanistic studies shows that PLH activate Wnt/ß-catenin signaling pathway to inhibit the adipogenesis. The study suggested that PLH inhibited adipogenesis during the early phase of differentiation by targeting mitotic clonal expansion and arresting the cell cycle in the G1 phase of the cell cycle. It improved the dyslipidemic condition in HFD-fed hamsters by decreasing the body weight, fat mass, eWAT weight and improving the serum lipid profile. Overall, PLH has been found as a potential drug candidate and a pharmacophore for combating metabolic disorders including obesity and dyslipidemia.
