Random screening is an early drug discovery approach where diverse chemical or natural compound libraries are tested in unbiased bioassays to find active “hits”. For B.Pharm students, understanding random screening connects concepts in pharmacology, medicinal chemistry, high-throughput screening, assay design, hit identification, lead generation, toxicity profiling and structure–activity relationships. This method complements target-based and phenotypic … Read more

Rational approaches to lead discovery based on traditional medicine integrate ethnopharmacology, pharmacognosy and modern drug‑discovery tools to identify, validate and optimize bioactive natural products. B.Pharm students should understand bioassay‑guided fractionation, dereplication, phytochemical screening, metabolomics, molecular docking, SAR and ADMET profiling to translate folk claims into credible drug leads. Emphasis on standardization, voucher specimens, quality control, … Read more
