Structure and Biological Activities: Steroid Moieties

ABSTRACT A steroid is a type of organic compound that contains a characteristic arrangement of four cycloalkane rings that are joined to each other. The core of steroids is composed of twenty carbon atoms bonded together that take the form of four fused rings, three cyclohexane rings and one cyclopentane ring. The steroids vary by the functional groups attached to this four-ring core and by the oxidation state of the rings. Steroid derivatives have occupied a unique place in the field of medicinal chemistry for their therapeutic values. This articles aims to review the work reported, their chemistry and biological activities of Steroid derivatives during past years
