Carbetimer is a partially imidized copolymer of ethylene & maleic anhydride with average MW approx 1,200 daltons; capable of specific stimulation of immune response. Carbetimer is a low molecular weight polymer derived from ethylene and maleic anhydride with potent antineoplastic activity. Preclinical studies have shown antitumor effects against many tumor cell lines including B 16 melanoma. Its antitumor actions are felt to include both reduction of uridine and cytidine nucleoside triphosphate as well as the diminution of pyrimidine salvage by inhibiting uridine, cytidine, and thymidine kinase. Besides direct antiproliferative effects, Carbetimer could act through immunomodulation, as suggested by the induction of cytotoxic T-cells in mice and the discordant in vitro and in vivo activities against the Lewis lung carcinoma model.

Brivudine monophosphate is a phosphate ester of Brivudine. Brivudine, also known as bromovinyl-deoxyuridine, is a uridine derivative and nucleoside analog with pro-apoptotic and chemosensitizing properties. In vitro, bromovinyl-deoxyuridine (BVDU) has been shown to downregulate the multifunctional DNA repair enzyme APEX nuclease 1, resulting in the inhibition of DNA repair and the induction of apoptosis. In addition, this agent may inhibit the expression of STAT3 (signal transducer and activator of transcription 3), which may result in the downregulation of vascular endothelial growth factor (VEGF). BVDU has also been found to inhibit the upregulation of chemoresistance genes (Mdr1 and DHFR) during chemotherapy.

ent-Abacavir is an enatiomer of Abacavir. Abacavir is a carbocyclic 2'-deoxyguanosine nucleoside reverse transcriptase inhibitor and an anti-HIV drug used to treat HIV infection. Intracellular enzymes convert Abacavir to its active form, carbovir-triphosphate (CBV-TP), which then selectively inhibits HIV reverse transcriptase by incorporating into viral DNA. Abacavir is metabolized in the liver by uridine diphosphate glucuronyltransferase and alcohol dehydrogenase resulting in inactive glucuronide and carboxylate metabolites, respectively.
