The phytochemical, biological, and medicinal attributes of phytoecdysteroids: An updated review.

ABSTRACT: The phytoecdysteroids (PEs) comprise a large group of biologically-active plant steroids, which have structures similar to those of insect-molting hormones. PEs are distributed in plants as secondary metabolites that offer protection against phytophagus (plant-eating) insects. When insects consume the plants containing these chemicals, they promptly molt and undergo metabolic destruction; the insects eventually die. Chemically, ecdysteroids are a group of polyhydroxylated ketosteroids that are structurally similar to androgens. The carbon skeleton of ecdysteroids is termed as cyclopentanoperhydro-phenanthrene with a β-side chain at carbon-17. The essential characteristics of ecdysteroids are a cis-(5β-H) junction of rings A and B, a 7-en-6-one chromophore, and a tra
