Antineoplastic

Epothilons A is a 16-membered macrolide antibiotic produced by the myxobacterium Sorangium cellulosum. It has strong cytotoxicity and has the effect of resisting plant pathogenic fungi.

It is produced by the strain of Streptomyces distallicus NCIB 8936. It has the activity against gram-positive bacterium, mycobacterium, dermatophyte and Trichophyte. It has inhibitory effects on solid tumors such as Epstein-Barr ascites carcinoma, sarcoma 180, Walker 258, oberling-Guerin osteoma, and also inhibits vaccinosis virus, herpes simplex virus, adenovirus, and mouse hepatitis virus in cell culture.

It is produced by the strain of Streptomyces echinatus. It has the activity of anti-gram-positive bacteria and vaginal trichomonas, and also has the effect on influenza virus and sarcoma 180 cells in vitro.

Illudin M is a natural sesquiterpene agent with strong anti-tumour activity.

KRX-0601, also known as UCN-01, is a synthetic derivative of staurosporine with antineoplastic activity. It inhibits many phosphokinases, including the serine/threonine kinase AKT, calcium-dependent protein kinase C, and cyclin-dependent kinases. This agent arrests tumor cells in the G1/S of the cell cycle and prevents nucleotide excision repair by inhibiting the G2 checkpoint kinase chk1, resulting apoptosis.

Rhodomycin A is originally isolated from Str. purpurascens 340. It has the activity of anti-gram-positive bacteria and weak effect on anti-gram-negative bacteria and fungi.

Safracin B is a new antibiotic from the family of Safracin produced by Pseudomonas fluorescens A2-2. Safracin B exhibits broad spectrum antimicrobial and strong antitumor activities.

Mithramycin A is an antineoplastic antibiotic produced by Streptomyces plicatus. Mithramycin A is a polymerase inhibitor that binds to GC rich sequences located in the minor groove of DNA.

Porfiromycin is a quinone antibiotic produced by Str. ardus NRRL 2817. It has anti-Gram-positive and negative bacteria activity. It can inhibit sarcoma-180, Ehrlich ascites carcinoma, L-1210, H leukemia (solid type). The dose of inhibiting KB cell protein synthesis is 0.5 μg/mL. It is a bioreductive DNA alkylating agent that preferentially kills hypoxic tumor cells relative to other aerobic counterparts.

Netropsin is isolated from Streptomyces netropsis as a basic polypeptide. It can specific bind to A-T areas of DNA that is very useful to genetic research. Netropsin can disrupt the cell cycle, prolonging G and arresting in G. Netropsin has antibiotic and antiviral activity. It has been shown that Netropsin is active against Gram-positive and Gram-negative bacteria.

It is produced by the strain of Str. pactum var. pactum NRRL 2939. It is a cyclopentane and cyclohexane derivative antibiotic. It has anti-bacterial, virus, tumor activity.

It is produced by the strain of Streptoverticillium verticillum 843-1. It's a heteropeptide antibiotic. It has anti-gram-positive bacteria, negative bacteria and mycobacterium effects. The therapeutic index of the complex for Solid Adenocarcinoma and Sarcoma-180 are 16. The therapeutic index of Ehrlician ascites cancer is 4-8. It acts an antibiotic originally, an anticancer agent and a selection agent for transformed algae, protista, animal and fungal cells.

A hydrophobic cyclodepsipeptide with potent antitumour activity; a highly selective potassium ionophore; a biosensor to detect potassium efflux.

Tallysomycin A is a glycopeptide antibiotic produced by the rare actinomycete No. E 465-94. It has anti-gram-positive bacteria and gram-negative bacteria and fungi activity. It can induce lysogenic E. coli W1709 (A) to release phage.

Bleomycin A5 hydrochloride is an antitumor antibiotic which induces apoptosis.

Pentostatin is an adenosine deaminase inhibitor isolated from Streptomyces and effective against cancer cell lines. Pentostatin is a purine nucleoside analog that irreversibly inhibits adenosine deaminase (Ki = 0.9 pM) and thus interrupts DNA synthesis in dividing cells. Pentostatin has been reported to display strong efficacy in the clinical treatment of hairy cell leukemia as well as relapsed chronic lymphocytic leukemia.

An unusual anthracycline produced by streptomyces nogalater var. Nogalater. It is a potent antibacterial and antitumor agent that interacts with DNA by intercalation.

Berubicin has potential antineoplastic activity. Berubicin intercalates into DNA and interrupts topoisomerase II activity, resulting in the inhibition of DNA replication and repair, and RNA and protein synthesis.

Epothilone C is a novel microtubule inhibitor and acts as an antineoplastic agent. Epothilones are originally isolated from cellulose-degrading myxobacterium Sorangium cellulosum.

Bafilomycins are a family of macrolide antibiotics isolated from Streptomycetes sp. They exhibits antitumor, antiparasitic, immunosuppressant and antifungal activity.
