Geldanamycin is a benzoquinone ansamycin antibiotic that inhibits heat shock protein 90 (HSP90). Geldanamycin has been shown to promote survival of neural stem cells from oxidative stress via inhibition of HSP90. It displays potent antineoplastic properties and inhibits myeloma cell growth.

Brefeldin is an antibiotic produced by Penicillum brefeldianum S-464, Pen. cyaneum S-ll, Pen. decumbens, Pen. simplicissimum S-543, etc. Brefeldin A has anti-candida, aspergillus and anti-tumor activity.

Doxorubicin is an anthracycline antibiotic with antineoplastic activity produced by the bacterium Streptomyces peucetius var. Doxorubicin is an antibiotic agent that inhibits DNA topoisomerase II and induces DNA damage and apoptosis.

Deoxynojirimycin inhibits mammalian glucosidase 1. As well, it inhibits intestinal and lysosmal alpha-glucosidases, beta-glucosidase from sweet almonds, pancreatic alpha-amylase and amyloglucosidase.

Rapamycin is an mTOR inhibitor immunosuppressant and kinase inhibitor with both antifungal and antineoplastic properties. It selectively inhibits the transcriptional activation of cytokines.

Fidaxomicin (OPT-80; PAR-101) is a new class of narrow spectrum macrocyclic antibiotic drug; selective eradication of pathogenic Clostridium difficile with minimal disruption to the multiple species of bacteria that make up the normal, healthy intestinal flora.

Maytansinol is an ansamacrolide isolated from P. verrucose. It was shown to inhibit microtubule assembly and induces microtubule disassembly in vitro. It exhibits antitumor activity.

Plitidepsin is a cyclic depsipeptide isolated from the marine tunicate Aplidium albicans. Plitidepsin shows potent anticancer activity against a large variety of cultured human cancer cells, inducing apoptosis by triggering mitochondrial cytochrome c release, initiating the Fas/DC95, JNK pathway and activating caspase 3 activation. This agent also inhibits elongation factor 1-a, thereby interfering with protein synthesis, and induces G1 arrest and G2 blockade, thereby inhibiting tumor cell growth.

It is produced by the strain of Nocardia sp. C-15003(N-1). It has the function of anti-tumor, anti-plant pathogenic fungi, skin fungi and protozoa, and has no antibacterial activity.

Calicheamicins are a class of enediyne antitumor antibiotics derived from the bacterium Micromonospora echinospora, The main component is calicheamicin γ1. It has strong anti-Gram-positive bacteria activity and anti-tumor effect.

It is a potent cell cycle inhibitor isolated from Pseudomonas sp. No.2663. It exhibits potent antitumor activities against tumor cell lines via binding to the spliceosome and modulating pre-mRNA splicing.

a potent anti-fungal antibiotic. Leptomycin B is an inhibitor of export protein CRM1.

Exatecan mesylate is a semisynthetic, water-soluble derivative of camptothecin with antineoplastic activity. Exatecan mesylate inhibits topoisomerase I activity by stabilizing the cleavable complex between topoisomerase I and DNA and inhibiting the religation of DNA breaks, thereby inhibiting DNA replication and triggering apoptotic cell death. This agent does not require enzymatic activation and exhibits greater potency than camptothecin and other camptothecin analogs.

An isomer of the nucleoside uridine found in all species and in many classes of RNA except mRNA. It is formed by enzymes called synthases, which post-transcriptionally isomerize specific uridine residues in RNA in a process termed pseudouridylation. Studies suggest that Beta-Pseudouridine reduces radiation-induced chromosome aberrations in human lymphocytes.
