Bioactivity-Guided Isolation and Identification of Anti-adipogenic Constituents from the n-Butanol Fraction of Cissus quadrangularis

Obesity is marked by the buildup of fat in adipose tissue that increases body weight and the risk of many associated health problems, including diabetes and cardiovascular disease. Treatment options for obesity are limited, and available medications have many side effects. Thus there is a great need to find alternative medicines for treating obesity. This study explores the anti-adipogenic potential of the n-butanol fraction of Cissus quadrangularis (CQ-B) on 3T3-L1 mouse preadipocyte cell line. The expression of various lipogenic marker genes such as adiponectin, peroxisome proliferator-activated receptor gamma, leptin, fatty acid-binding proteins, sterol regulatory element-binding proteins, fetal alcohol syndrome, steroyl-CoA desaturase-1, lipoproteins, acetyl-CoA carboxylase alpha, and acetyl-CoA carboxylase beta were variously significantly downregulated. After establishing the anti-adipogenic potential of CQ-B, it was fractionated to isolate anti-adipogenic compounds. We observed significant reduction in neutral lipid content of differentiated cells treated with various fractions of CQ-B. Gas chromatography-mass spectrometry analysis revealed the presence of thirteen compounds with reported anti-adipogenic activities. Further studies to purify these compounds can offer efficacious and viable treatment options for obesity and related complications.
