4 Pharmacology and Biochemistry
4.1 MeSH Pharmacological Classification

Affinity Labels

Analogs of those substrates or compounds which bind naturally at the active sites of proteins, enzymes, antibodies, steroids, or physiological receptors. These analogs form a stable covalent bond at the binding site, thereby acting as inhibitors of the proteins or steroids. (See all compounds classified as Affinity Labels.)


Anticarcinogenic Agents

Agents that reduce the frequency or rate of spontaneous or induced tumors independently of the mechanism involved. (See all compounds classified as Anticarcinogenic Agents.)
