The endocrine system is a chemical messenger system comprising feedback loops of the hormones released by internal glands of an organism directly into the circulatory system, regulating distant target organs. Hormones are chemicals that serve to communicate between organs and tissues for physiological regulation and behavioral activities. Hormones affect distant cells by binding to specific receptor proteins in the target cell, resulting in a change in cell function.

The endocrine system is concerned with the integration of developmental events proliferation, growth, and differentiation, and the psychological or behavioral activities of metabolism, growth and development, tissue function, sleep, digestion, respiration, excretion, mood, stress, lactation, movement, reproduction, and sensory perception caused by hormones. Irregulated hormone release, inappropriate response to signaling or lack of a gland can lead to endocrine disease.

MCE offers a unique collection of 874 endocrinology related compounds targeting varieties of hormone receptors such as thyroid hormone receptor, TSH receptor, GNRH receptor, adrenergic receptor, etc. MCE Endocrinology Compound Library is a useful tool for the discovery of endocrinology drugs.
