Betamethasone Dipropionate is the 17, 21-dipropionate ester of betamethasone, a synthetic glucocorticoid with metabolic, immunosuppressive and anti-inflammatory actions. Betamethasone dipropionate (SCH 11460) binds to specific intracellular glucocorticoid receptors and subsequently binds to DNA to modify gene expression. The synthesis of certain anti-inflammatory proteins is induced while the synthesis of certain inflammatory mediators is inhibited. As a result, there is an overall reduction in chronic inflammation and autoimmune reactions.

ISA-2011B is an inhibitor of PIP5K1α. It also has promising anticancer effects.

Iodophenpropit dihydrobromide is an effective and selective antagonist of the histamine H3 receptor. The binding of [125I]Iodophenpropit is readily reversible, selective, and of high affinity (KD: 0.32 nM).

Ipenoxazone is an effective and centrally acting muscle relaxant.

IPI-3063 is an effective and selective inhibitor of PI3K p110δ (IC50: 2.5 ± 1.2 nM).

MKC8866 is a selective IRE1 RNase inhibitor (IC50: 0.29 μM in human vitro). MKC8866 inhibits IRE1 RNase in breast cancer cells leading to the decreased production of pro-tumorigenic factors and it can inhibit prostate cancer (PCa) tumor growth.

IRL-1620 is an effective and selective agonist of endothelin receptor type B (ETB) (Ki: 16 pM).

IRL-1620 acetate is an effective and selective agonist of Endothelin B receptor (ETB) with a Ki of 16 pM which is more selective than ETA with a Ki of 19 μM.

IRL 2500 is an antagonist of Endothelin receptor with IC50s of 1.3 and 94 nM for Endothelin A receptor and Endothelin B receptor.

Istaroxime hydrochloride (PST2744 hydrochloride) is a Na+/K+-ATPase inhibitor and sarcoplasmic/endoplasmic reticulum calcium ATPase 2 (SERCA 2) activator, a novel positive inotropic compound that can be used to study acute heart failure.
