Insight into the Isolation, Synthesis, and Structure-Activity Relationship of Piperine Derivatives for the Development of New Compounds: Recent Updates

Currently, black pepper commands the leading position among all the spices as a spice of great commercial importance in all the world trade and finds its way into the dietary habits of millions of people worldwide. Black pepper is biologically known as Piper nigrum and contains piperine as the main active chemical constituent. This paper highlights various general methods for extracting piperine from the crude drug such as maceration extraction, hydrotropic extraction, accelerated solvent extraction, thin-layer chromatography, and extraction with ethanol & dichloromethane Ionic fluid-based ultrasonic-assisted extraction, etc. In this review, piperine and its analogs exhibit numerous pharmacological activities and synthetic schemes of insecticidal activity, anti-cancer activity, anti-inflammatory activity, anti-diabetic activity, anti-hyperlipidemic activity, antifungal activity, narcotic activity, etc. and its structure-activity relationship. The biochemistry of piperine has also been summarized in the presented article. This very exhaustive review details the complete information about piperine, its derivatives, and further processing. Furthermore, the current study summarises recent research that has linked piperine to its use as a treatment for a variety of ailments.
