246573 6,7-Dihydroxycoumarin 98%  
B5507 Bleomycin sulfate from Streptomyces verticillus crystalline, 1.5-2.0 units/mg solid Bleomycin sulfate binds to DNA, causes ssDNA scission at specific base sequences and inhibits DNA synthesis. This inhibitory action requires bleomycin to bind oxygen and a metal ion. It can also cleave RNA, to a lesser degree but more selectively. It acts as an inducer and regulator of apoptosis and inhibits tumor angiogenesis.
C2538 Carboplatin Carboplatin is a platinum-based antineoplastic drug that damages DNA by forming intrastrand cross-links with neighboring guanine residues. Tumors acquire resistance to these drugs through the loss of DNA-mismatch repair (MMR) activity and the resultant decrease in the induction of programmed cell death.
C0400 Carmustine ≥98% Carmustine is a DNA alkylating agent causing DNA interstrand crosslinks. Effective against glioma and other solid tumors.
C0253 Chlorambucil Chlorambucil is an anti-cancer drug that alkylates DNA and induces apoptosis. Death of chronic lymphocytic leukemia cells occurs via a p53-dependent mechanism.
C7397 Cyclophosphamide monohydrate ISOPAC® Cyclophosphamide is a cytotoxic nitrogen mustard derivative widely used in cancer chemotherapy. It cross-links DNA, causes strand breakage, and induces mutations. Its clinical activity is associated with a decrease in aldehyde dehydrogenase 1 (ALDH1) activity.
D2390 Dacarbazine antineoplastic purine analog Dacarbazine is a purine analog of naturally occurring purine precursor 5-amino-1H-imidazole-4-carboxamide (AIC). It is a synthetic triazine antineoplastic agent that exerts cytotoxic effects by acting as an alkylating agent and by inhibiting DNA synthesis and inducing apoptosis. It is known to induce hepatotoxicity in mice. Dacarbazine is not cell cycle-phase specific.
I4909 Ifosfamide ≥98% Ifosfamide is a nitrogen mustard compound that is a structural isomer of cyclophosphamide. Ifosfamide is a prodrug that must be transformed by cytochrome P450 to the biologically active component. It is used as an antineoplastic agent in cancer chemotherapy, but ifosfamide is more likely to cause renal toxicity than cyclophosphamide.
L5918 Lomustine ≥98% Antineoplastic agent with cellular DNA effects. Lomustine induces p53 expression in A2870 cells.
M2011 Melphalan powder In rat, melphalan in isolated lung perfusion (ILP) functions as a potent therapeutics for sarcomatous pulmonary metastases. It forms DNA intrastrand crosslinks by bifunctional alkylation in 5′-GGC sequences. Melphalan acts as a bone-marrow depressant and is implicated in the treatment of multiple myeloma and ovarian cancer.
M0503 Mitomycin C from Streptomyces caespitosus powder, contains NaCl as solubilizer Mode of Action: This product is an alkylating agent that specifically targets the guanine nucleoside sequence 5′-CpG-3′. It inhibits DNA synthesis by covalently reacting with DNA, forming crosslinks between complementary strands of DNA. This interaction prevents separation of complementary DNA strands, inhibiting DNA replication.

Antimicrobial Spectrum: Mitomycin C has strong antitumor activity, especially against Ehrlich ascites tumor cells, and strong bactericidal action against gram-positive and gram-negative bacteria.
M6545 Mitoxantrone dihydrochloride ≥97% (HPLC) Mitoxantrone is a cytostatic anthracenedione that intercalates in DNA and increases the incidence of double-strand breaks by stabilizing the cleavable complex of topoisomerase II and DNA. Mitoxantrone also displays broad immunosuppressive activity inhibiting proliferation of all classes of lymphocytes and inducing apoptosis of antigen-presenting T cells. It used clinically as a chemotherapeutic agent against leukemias and solid tumors and as an immune system modulator in multiple sclerosis.
O9512 Oxaliplatin solid Oxaliplatin is an anti-tumor agent with activity against colorectal cancer; cytotoxicity follows the formation of adducts with DNA.
P4394 cis-Diammineplatinum(II) dichloride crystalline Potent chemoimmunotherapeutic drug; stimulates the immune responses by activating macrophages and other cells of the immune system. Cisplatin-treated macrophages show increased antigen presentation function in vitro. Treatment increased cellular NF-κB content and translocation in macrophages. Cisplatin effects are regulated by kinases, phosphatases, and Ca2+/calmodulin. Forms cytotoxic adducts with the DNA dinucleotide d(pGpG), inducing intrastrand crosslinks.
Potent platinum-based antineoplastic agent. Forms cytotoxic adducts with the DNA dinucleotide d(pGpG), inducing intrastrand cross-links.
