β-estradiol is a potent mammalian estrogenic hormone produced by the ovary. Triggers the production of gonadotropins leading to ovulation. β-Estradiol is used to study cell differentiation and transformations (tumorigenicity). The pharmacology and HPLC determination of β-Estradiol…

Hydrocortisone, a primary glucocorticoid secreted by the adrenal cortex. It has three times the anti-inflammatory potency of corticosterone but much lower Na2+ retention potency. Hydrocortisone, known more formally as cortisone (INN, USAN, BAN), is a steroid hormone, produced by the zona…

An atypical, second generation antipsychotic compound that has effects at multiple receptors; antagonizes dopamine D1, D2, and D3 receptors, serotonin 5-HT1A, 5-HT2A, and 5-HT7 receptors, and α1A, α1B, and α2C adrenergic receptors.

A synthetic intermediate useful for pharmaceutical synthesis.

L-Citrulline is a by product of NO formation from metabolism of L-arginine that exhibits tocolytic and antioxidative activities. L-Citrulline was originally found in watermelon. In isolated rat uteri, L-citrulline decreases uterine contractile force through stimulation of the NO-cGMP relaxant…

An antimycotic prodrug that is converted by cytosine deaminase to 5-fluorouracil, a cytotoxic drug that inhibits viral infections and has cytotoxic effects on cancer cells.

A broad-spectrum β-lactam antibiotic used for parenteral administration.

A selective estrogen receptor (ER) modulator; an ER antagonist in breast tissue, effective in treating early breast cancer; an ER agonist in bone and blood vessels and a partial ER agonist in uterine tissues.

An analog of thalidomide that, at 10 μM, alters gene expression and cell viability in a range of cancer cell lines; induces proliferation and enhances the functional capacity of T-lymphocytes, amplifying co-stimulatory signaling pathways.

A synthetic intermediate useful for pharmaceutical synthesis.

A chemiluminescent substrate of firefly luciferase which produces light upon oxidative decarboxylation in the presence of ATP.

A cell-permeable antagonist of IP3 receptors.

2-(hydroxymethyl)-Pyrimidine is a synthetic intermediate useful for pharmaceutical synthesis.

A dihydropyridine L-type calcium channel antagonist that displays antihypertensive and antianginal activity; selectively inhibits adenosine A3 receptors (Ki = 3.25 µM) and CYP3A4 catalytic activity (IC₅₀ = 0.148 µM); activates TRPA1 channels, producing an increase in Ca2+…

A major metabolite of glycyrrhizin, a constituent of licorice that exhibits anti-ulcerative, anti-inflammatory, and immunomodulatory properties; at 100 mg/kg/day, reduces lipid peroxidation and increases antioxidant activity in diabetic rats; suppresses LPS-induced TNF-α production and…

A mixture of at least four closely related components, polymyxin B1 to B4, with polymyxin B1 and B2 being the two major components; demonstrates rapid in vitro bactericidal activity against major multidrug-resistant Gram-negative bacteria, including P. aeruginosa, A. baumannii, and K. pneumonia.

An HDAC inhibitor of class I and class II HDACs at around 50 nM; arrests cell growth in a wide variety of transformed cells in culture at 2.5-5.0 µM.

A natural product which effectively kills malarial parasites of the genus Plasmodium (IC50 = 4.0 nM); also used against a wide range of trematodes, including Schistosoma; has potential applications in certain types of cancer and inflammatory conditions.

A broad-spectrum nitrofuran antibiotic used against urinary tract infections and as therapy for acute diarrhea of bacterial origin; inhibits the survival and migration of cancer cells, suppressing tumor growth and metastasis in vivo, at least in part by inhibiting STAT3 (IC₅₀ = 10 µM).

An indoleamine neurohormone whose levels vary in a daily cycle, thereby allowing the entrainment of the circadian rhythms of several biological functions in animals, plants, and microbes; acts as a powerful antioxidant that protects lipids, proteins, and DNA against oxidative damage.

Induces protein expression where the gene is under the control of the lac operator by triggering transcription of the lac operon in cloning procedures.
