Imatinib is a multi-target inhibitor of v-Abl, c-Kit and PDGFR with IC50 of 0.6 μM, 0.1 μM and 0.1 μM, respectively. Imatinib is used to treat chronic myelogenous leukemia (CML), gastrointestinal stromal tumors (GISTs) and a number of other malignancies.

Imiquimod is an immune response modifier that acts as a toll-like receptor 7 agonist and is commonly used topically to treat warts on the skin of the genital and anal areas.

Indapamide (Lozol)

Indole-3-carbinol

Indomethacin (Indocid, Indocin)

Inhibitor of ATP-sensitive K+ channel activity in MIN 6 cells. Has also been shown to bind sulfonylurea receptors as well.

Inhibits bone resorption as a sodium salt and complexed with technetium Tc 99m for bone imaging. The monophosphonates are not active and the biphosphonates are used in disorders affecting the skeleton such as metastatic disease, asteoporosis and Paget's.

Ipratropium bromide

Irsogladine maleate is a selective PDE4 inhibitor that facilitates gap junction intercellular communication through muscarinic acetylcholine receptor binding. It is a potent inhibitor of angiogenesis in wild-type and plasminogen activator-deficient mice.

Isepamicin

Isoliquiritigenin

Isoniazid is an antibacterial agent used primarily as a tuberculostatic.Target: AntibacterialIsoniazid is a prodrug and must be activated by a bacterial catalase-peroxidase enzyme that in M. tuberculosis is called KatG [1]. KatG couples the isonicotinic acyl with NADH to form isonicotinic acyl-NADH complex. This complex binds tightly to the enoyl-acyl carrier protein reductase known as InhA, thereby blocking the natural enoyl-AcpM substrate and the action of fatty acid synthase. This process inhibits the synthesis of mycolic acid, required for the mycobacterial cell wall. A range of radicals are produced by KatG activation of isoniazid, including nitric oxide, which has also been shown to be important in the action of another antimycobacterial prodrug PA-824 [2, 3]. Isoniazid is bactericidal to rapidly dividing mycobacteria, but is bacteriostatic if the mycobacteria are slow-growing [4].

Isoprenaline Hydrochloride is a non-selective beta-adrenergic agonist and structurally similar to adrenaline.

Isosorbide mononitrate(Isosorbide-5-mononitrate) is a nitrate-class compound used for angina pectoris; acts by dilating the blood vessels so as to reduce the blood pressure.

Isotretinoin(13-cis-Retinoic acid) is a medication used for the treatment of severe acne. It was first developed to be used as a chemotherapy medication for the treatment of brain cancer, pancreatic cancer and more.
