We are offering paclitaxel. Paclitaxel 98%hplc paclitaxel iso 9001:2000 professional production experience paclitaxel cas no.:33069-62-4 chemical name: paclitaxel cas number: 33069-62-4 molecular formula: c15h24n202 molecular weight: 264.36 purity: 99% appearance: white crystalline powder applications/function:paclitaxel is a mitotic inhibitor used in cancer chemotherapy. It was discovered in a national cancer institute program at the research triangle institute in 1967 when monroe e. Wall and mansukh c. Wani isolated it from the bark of the pacific yew tree, taxus brevifolia and named it 'taxol'. When it was developed commercially by bristol-myers squibb (bms) the generic name was changed to 'paclitaxel' and the bms compound is sold under the trademark 'taxol'. In this formulation, paclitaxel is dissolved in cremophor el and ethanol, as a delivery agent. A newer formulation, in which paclitaxel is bound to albumin, is sold under the trademark abraxane. Paclitaxel is now used to treat patients with lung, ovarian, breast cancer, head and neck cancer, and advanced forms of kaposi's sarcoma. Paclitaxel is also used for the prevention of restenosis. Paclitaxel stabilizes microtubules and as a result, interferes with the normal breakdown of microtubules during cell division. Together with docetaxel, it forms the drug category of the taxanes.

We are offering vancomycin hydrochloride. Vancomycin hcl specification: package: product description application: vancomycin is a glycopeptide antibiotic isolated from the soil microorganism streptomyces orientalis. Since the 1950s it has been given primarily to treat severe infections caused by gram-positive organisms.its administration has increased due to the emergence of methicillin-resistant strains of staphylococcus aureus and staphylococcus epidermidis. The increase has occurred worldwide, reaching nearly 10-fold in the united state since 1984. Antimicrobial spectrum: interferes with cell wall synthesis.

We are offering metronidazole, methyl, nitroimidazole, ethanol. 1.name:metronidazole 2.cas no.:443-48-1 3.mf.:c6h9n3o3 4.standards:bp 5.appearance:white or yellowish, crystalline powder 6.metronidazole is slightly soluble in water, in acetone, in alcohol and in methylene chloride 7.mechaninsm of action:metronidazole, taken up by diffusion, is selectively absorbed by anaerobic bacteria and sensitive protozoas.metronidazole, taken up by diffusion, is selectively absorbed by and sensitive . Once taken up by anaerobes, it isnon-enzymatically reduced by reacting with reduced , which is generated by pyruvate oxido-reductase. This reduction causes the production of toxic products to anaerobic cells, and allows for selective accumulation in anaerobes.the metronidazole metabolites are taken up into bacterial dna, and form unstable molecules. This function only occurs when metronidazole is partially reduced, and because this reduction usually happens only in anaerobic cells, it has relatively little effect upon human cells or aerobic bacteria.
