Chromens are naturally occurring or synthetically obtaining compounds and these are oxygen containing heterocycles, abundantly found in nature in the form of flavone, isoflavones, flavanones, catechins, anthocyanins and collectively known as flavonoids and isoflavonoids. A large number of synthetic analogues of chromenones have been evaluated for their anticancer, anticonvulsant, angioprotective, antiallergic, antihistaminic, antimicrobial, antioxidant, anti-HIV etc activity. A variety of cellular targets (receptors) are interacting with the derivatives of benzopyran moiety and that can be responsible for their wide ranging biological activities. The motive of the present paper on chromen and there derivatives was to review the available information on this field.
