Canrenoate potassium (Soldactone) is a synthetic pregnadiene derivative with anti-aldosterone activity.

Sulbactam sodium (CP-45899-2) (Unasyn) is an irreversible β-lactamase inhibitor.

Slingshot inhibitor D3 (JHN76359) is a potent inhibitor of the Protein Phosphatase Slingshot.

Sulbactam (CP45899) is a semi-synthetic beta-lactamase inhibitor. The beta-lactam ring of sulbactam irreversibly binds to beta-lactamase at or near its active site, thereby blocking enzyme activity and preventing metabolism of other beta-lactam antibiotics by the enzyme. Combining this agent with a beta-lactamase susceptible antibiotic, such as penicillins or a cephalosporin, to treat infections caused by beta-lactamase producing organisms, results in a decreased turnover rate of the beta-lactamase sensitive antibiotic and enhances its antibacterial activity.

5,7-Dichlorokynurenic acid (5,7-dichlorokynurenic acid sodium) is an NMDA receptor antagonist.

Bicuculline is an alkaloid extracted from Corydalis decumbens, acting as a competitive antagonist of the neurotransmitter GABAA receptor (IC50 = 2 μM).

Bicuculline has anticonvulsant effects and is commonly used to establish mouse seizure models.

NU2058 (O(6)-Cyclohexylmethylguanine) is a guanine-based CDK inhibitor, also inhibits DNA topoisomerase II ATPase activity.

SPI-112, the SPI-112 methyl ester analog, can inhibit cellular Shp2 PTP activity. SPI-112 bound to Shp2 by surface plasmon resonance (SPR) and displayed competitive inhibitor kinetics to Shp2.

U0126-etoh (U0126 Ethanol) is a non-ATP competitive inhibitor of MEK1 (IC50=72 nM) and MEK2 (IC50=58 nM) with selectivity. U0126-EtOH inhibited autophagy and mitophagy.

DNQX (FG 9041) is a competitive, non-NMDA glutamate receptor antagonist (IC50s = 0.5 and 0.1 μM for AMPA and kainate receptors, respectively)

Vonoprazan (TAK-438 (free base)) is an orally active potassium-competitive acid blocker.Vonoprazan can be used for the treatment of gastroduodenal ulcer and reflux esophagitis
