Phytochemicals and adipogenesis
Obesity is an increasing health problem all over the world. Phytochemicals are potential agents to inhibit differentiation of preadipocytes, stimulate lipolysis, and induce apoptosis of existing adipocytes, thereby reducing the amount of adipose tissue. Flavonoids and stilbenoids represent the most researched groups of phytochemicals with regards to their effect on adipogenesis, but there are also a number of in vitro and in vivo studies with phenolic acids, alkaloids, and vitamins, as well as other plant compounds. Although phytochemicals like epigallocatechin-3-gallate, genistein, and resveratrol reduce lipid accumulation and induce adipocyte apoptosis in vitro and reduce body weight and adipose tissues mass in animal models of diet-induced obesity, well-conducted clinical trials are lacking. Pharmacological doses are often used in vitro and when applied in physiological doses in animals or humans, the phytochemicals are often ineffective in affecting adipogenesis. However, by combining several phytochemicals or using them as templates for synthesizing new drugs, there is a large potential in targeting adipogenesis using phytochemicals.
