Bioactive small molecules are organic compounds that have a low molecular weight (900 daltons). Most pharmaceutical drugs are small molecules. Larger structures such as nucleic acids, proteins, and many polysaccharides are not small molecules.
Isoniazid is a bactericidal and bacteriostatic agent against Mycobacterium tuberculosis, the causal agent of tuberculosis. It is a pyridine in structure. Mechanism of Action Isoniazid itself is not toxic to the bacterial cell, but acts as...
Tetramisole Hydrochloride (syn: DL-Levamisole) is a racemic mixture composed of 50% D- and 50% L-isomers of Levamisole. This compound is less potent than Levamisole Hydrochloride against parasites., and the D-isomer of the mixture contributes its...
Mitoxantrone Dihydrochloride is used for cancer research as a chemotherapeutic for leukemias and solid tumors. It has immunosuppressive activity and inhibits proliferation of lymphocytes and induces apoptosis of antigen-presenting T-cells...
Rapamycin (Sirolimus) is a natural compound belonging to the macrolide family. It is derived from Streptomyces hygroscopicus isolated from a soil sample from Easter Island in 1972 by Mr. Sehgal of Ayerst Research Labs in Montreal, Quebec...
