Prasterone is an endogenous steroid hormone that acts as an agonist at ERβ, NMDA, and σ1 receptors, a partial agonist at ERα and AR, and antagonist at GABA-A receptors. It displays a variety of biologocial activities, including enhancing working memory and cognition, inhibiting proliferation and migration of cervical cancer cells, increasing expression of various glutamate transporters to suppress seizures, and minimizing gastric acid secretion, lipid peroxidation and ulcer formation.

Dapiprazole HCl is an α1-Adrenergic receptor antagonist used to reverse mydriasis. It also decreases mean intraocular pressure, suppresses pigment shedding, and increases outflow facility.

Cyproconazole inhibits ergosterol biosynthesis in fungi.

Cypermethrin is a synthetic type II insecticide and protein phosphate inhibitor. It inhibits protein phosphates, inducing nerve blockade and paralysis.

Ancitabine HCl is a pyrimidine analog and DNA synthesis inhibitor previously used to treat leukemias. It inhibits proliferation of HSV-1 and CMV and induces degranulation of granular tubes.

Corticosterone is an endogenous steroid hormone involved in immune responses, stress responses and energy homeostasis. It activates mineralocorticoid and glucocorticoid receptors.

Colistin sulfate is a NADH quinone oxidoreductase inhibitor that induces formation of pores in membranes of gram negative bacteria. It is highly neurotoxic and nephrotoxic.

Clopidol is coccidiostat used to treat parasite infections in veterinary medicine.

Clofibric acid is a PPARα agonist, auxin inhibitor and metabolite of clofibrate used as a plant growth regulator. It also decreases production of cholesterol and activity of HMG-CoA reductase and ACAT. It also suppresses microvessel growth in ovarian cancer models.

Clindamycin Palmitate HCl a ribosomal translocation and protein synthesis inhibitor that displays efficacy against MRSA. It is also occasionally used to treat Plasmodium.

Ciglitazone is a PPARγ agonist. It is known to decrease insulin levels, VEGF production and blood pressure and induces cell cycle arrest in stomach cancer cells.

Chymostatin is a protease inhibitor used in research models.

Chromium picolinate is used to prevent chromium deficiency and to decrease serum glucose and insuline levels. It also decreases plasma lipid levels and platelet aggregation and improves myocardial contractility.

Chlormadinone acetate is a synthetic steroid hormone and antagonist at androgen and estrogen receptors used to treat BPH and polycystic ovary syndrome. It also promotes osteoblast differentiation and Ca deposition in bone marrow stem cells.

Cheirolin is an antioxidant and sulfonyl analog of sulforaphane. It induces phase II enzyme activity and expression.

Ceftiofur sodium is a penicillin binding protein inhibitor that prevents synthesis of bacterial cell walls. It also decreases LPS-induced expression of pro-inflammatory cytokines in endotoxemia models.

Cefotaxime Acid is a penicillin binding protein inhibitor that prevents peptidoglycan synthesis and bacterial cell wall formation. It is mostly resistant to β-lactamase activity.

Cefoperazone is a penicillin binding protein inhibitor and mammalian mRNA splicing inhibitor that prevents peptidoglycan synthesis and bacterial cell wall formation.

Cefaclor monohydrate is a penicillin binding protein inhibitor that prevents peptidoglycan synthesis and bacterial cell wall formation. It also enhances phagocytosis, bacterial activity of granulocytes and macrophages, and slows gastric emptying and intestinal transit.

Canrenone is a metabolite of spironolactone, Na/K ATPase partial agonist and aldosterone and androgen receptor antagonist used as a diuretic.

Cerulomycin A is a toxin that inhibits growth of Entamoeba. It may prevent proliferation of cancer cells, and suppresses immune responses.

Butein is found in Rhuteic verniciflua and Butea monosperma. It induces cell cycle arrest and apoptosis in lung cancer cells, inhibits vessel spouting from aortic rings, and prevents hepatic stellate cell activation.
