DC8951	4-NITROCATECHOL
DC9005	(S)-(+)-ketoprofen	Dexketoprofen works by blocking the action of a substance in the body called cyclo-oxygenase. It belongs to a class of medicines called non-steroidal anti-inflammatory drugs (NSAIDs).
DC9043	Pramipexole 2HCL monohydrate	Pramipexole dihydrochloride hydrate is a selective dopamine D2-type receptor agonist, with Kis of 2.2 nM, 3.9 nM, 0.5 nM and 1.3 nM for D2-type receptor, D2, D3 and D4 receptors, respectively. Pramipexole dihydrochloride hydrate can be used for the resear
DC9236	Brequinar	Brequinar (DUP785) is a potent inhibitor of dihydroorotate dehydrogenase (DHODH) with an IC50 of 5.2 nM for human DHODH. Brequinar has potent activities against a broad spectrum of viruses. Brequinar also has an anti-SARS2 activity.
DC9033	Zoledronic acid hydrate	Zoledronic acid monohydrate(CGP 42446; ZOL 446) is an activator of protein kinase C with apoptotic effects on multiple myeloma cell lines. It inhibited proliferation of human foetal osteoblastic cell line (hFOB) with an IC50 of 40 uM.
DCAPI1202	Vecuronium Bromide	Vecuronium Bromide
DC9003	Triamterene	Triamterene blocks epithelial Na+ channel (ENaC) in a voltage-dependent manner, which used as a mild diuretic.
DC9009	Thalidomide	Thalidomide can directly inhibit angiogenesis induced by bFGF or VEGF in vivo.
DCAPI1555	Teicoplanin	Teicoplanin Complex is a complex of antibiotics produced by Actinoplanes teichomyceticus. Teicoplanin, the major component of Teicoplanin Complex, is a glycopeptide antibiotic structurally similar to Vancomycin (sc-204938) and Ristocetin (sc-202318). As a
DCAPI1552	streptomycin	Streptomycin (Agrept) is an effective antibiotic against M. tuberculosis, is used for the research of tuberculosis (TB). Streptomycin also is a bacteriocidal agent that can be used for the research of a number of bacterial infections. Streptomycin can bind strongly to nucleic acids, interferes and blocks protein synthesis while permitting continued RNA and DNA synthesis. Streptomycin, as a common antibiotic used in culture media, also is a blocker of stretch-activated and mechanosensitive ion channels in neurons and cardiac myocytes .
