Phytochemicals in Drug Discovery: A Pharmacognosy Perspective

Abstract

The use of phytochemicals (the bioactive compounds sourced from the plant kingdom) has been instrumental in making modern medicine possible. The pharmaceutical sciences, through their scientific study of the medicinal drugs that are sourced from nature, has provided many of the foundational principles that have gone into understanding how phytochemicals can be used therapeutically. This article will explore why phytochemicals are critical to drug discovery by focusing on the chemical diversity, biological activity, and therapeutic application of phytochemicals for treating a variety of diseases. This article will also explain why traditional knowledge, modern extraction and analytical methodologies, and emerging technologies (e.g., bioinformatics and nanotechnology) have been developed to enhance the research of phytochemicals. This article discusses how challenges related to phytochemical drug development (e.g., standardization, sustainability, and clinical validation) must be overcome. This article will show that, through a pharmacognostic perspective, plant-derived compounds will continue to be relevant in the pharmaceutical industry and proposes future research directions for integrating traditional medicine with advanced pharmaceutical science techniques.
