| Diflomotecan | Diflomotecan is an E-ring modified camptothecin analogue, which possesses greater lactone stability in plasma compared with other topoisomerase I inhibitors. Diflomotecan is also a 10,11-difluoro-homocamptothecin, represents a new promising class of topoisomerase I inhibitors with enhanced plasma stability and superior preclinical anti-tumour activity as compared to the established camptothecins, irinotecan and topotecan. Diflomotecan was the first homocamptothecin to enter clinical studies. Phase I data are summarized for both the intravenous and oral schedules. The toxicity is primarily haematological while no severe gastrointestinal toxicity has been observed in contrast to other topoisomerase I inhibitors. Diflomotecan has a high oral bioavailability (72 - 95%) and the oral day 1 - 5 every 3 weeks regimen is recommended for Phase II testing because it is relatively well tolerated, convenient and mimics protracted exposure.

| Elomotecan | Elomotecan (BN-80927) belongs to a novel family of camptothecin analogs, the homocamptothecins, developed on the concept of topoisomerase I (Topo I) inhibition and characterized by a stable seven-membered beta-hydroxylactone ring. Preclinical data reported here show that BN80927 retains Topo I poisoning activity in cell-free assay (DNA relaxation) as well as in living cells, in which in vivo complexes of topoisomerase experiments and quantification of DNA-protein-complexes stabilization, have confirmed the higher potency of BN80927 as compared with the Topo I inhibitor SN38. In addition, BN80927 inhibits Topo II-mediated DNA relaxation in vitro but without cleavable-complex stabilizatio...th assays, BN80927 is a very potent antiproliferative agent as shown by IC(50) values consistently lower than those of SN38 in tumor cell lines as well as in their related drug-resistant lines. BN80927 shows high efficiency in vivo in tumor xenograft studies using human androgen-independent prostate tumors PC3 and DU145. Altogether, these data strongly support the clinical development of BN80927.

| Etirinotecan pegol | Etirinotecan pegol, also know as pegylated irinotecan, NKTR102, is a formulation of polyethylene glycol (PEG)-encapsulated irinotecan with antineoplastic activity. The prodrug irinotecan, a semisynthetic derivative of camptothecin, is converted to the biologically active metabolite 7-ethyl-10-hydroxy-camptothecin by a carboxylesterase-converting enzyme. One thousand-fold more potent than its parent compound irinotecan, 7-ethyl-10-hydroxy-camptothecin inhibits topoisomerase I activity by stabilizing the cleavable complex of topoisomerase I and DNA, resulting in DNA breaks that inhibit DNA replication and trigger apoptosis. Pegylation provides improved drug penetration into tumors and decreases drug clearance, thereby increasing the duration of therapeutic effects while lowering the toxicity profile. Synonyms: NKTR102; NKTR 102; NKTR-102; pegylated irinotecan NKTR 102; Etirinotecan pegol. CAS No. 1193151-09-5. Molecular formula: C161H196Cl4N20O40. Mole weight: 3193.24. | |
| Exatecan free base | Exatecan, also known as DX 8951, 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 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 analogues. Uses: Designed for use in research and industrial production. Additional or Alternative Names: DX 8951; DX 8951; DX 8951; Exatecan free base. Product Category: Others. Appearance: Solid powder. CAS No. 171335-80-1. Molecular formula: C24H22FN3O4.

| Gimatecan | Gimatecan is an orally bioavailable, semi-synthetic lipophilic analogue of camptothecin, a quinoline alkaloid extracted from the Asian tree Camptotheca acuminate, with potential antineoplastic and antiangiogenic activities. Gimatecan binds to and inhibits the activity of topoisomerase I, stabilizing the cleavable complex of topoisomerase I-DNA, which inhibits the religation of single-stranded DNA breaks generated by topoisomerase I; lethal double-stranded DNA breaks occur when the topoisomerase I-DNA complex is encountered by the DNA replication machinery, DNA replication is disrupted, and the tumor cell undergoes apoptosis. Although the mechanism of its antiangiogenic activity has yet to be full elucidated, this agent may inhibit endothelial cell migration, tumor neovascularization, and the expression of proangiogenic basic fibroblast growth factor (bFGF).

| Irinotecan, Hydrochloride Salt, Trihydrate ([1,4-Bipiperidine]-1-carboxylic Acid (S)-4, 11-diethyl-3, 4, 12, 14-tetrahydro-4-hydroxy-3, 14-dioxo-1H-pyrano[3, 4, 6, 7]indolizino[1, 2-b]quinolin-9-yl Ester, HCl Trihydrate) | Irinotecan (CPT-11) is a topoisomerase I inhibitor. It is a semisynthetic analog of the natural alkaloid camptothecin and has an active metabolite SN-38 (7-Ethyl-10-hydroxycamptothecin). During the S phase of the cell cycle, camptothecins selectively bind to and stabilize topoisomerase I-DNA complexes, inhibiting religation, causing the accumulation of topoisomerase I-mediated single-strand DNA breaks in the DNA, and producing irreversible double-strand DNA breaks that lead to cell death.

| Lurtotecan | liposomal lurtotecan is a liposome-encapsulated formulation of lurtotecan with antineoplastic activity. Lurtotecan, a semisynthetic analogue of camptothecin, selectively stabilizes the topoisomerase I-DNA covalent complex and forms an enzyme-drug-DNA ternary complex during S phase of the cell cycle, thereby inhibiting religation of topoisomerase I-mediated single-stranded DNA breaks. This ultimately results in an inhibition of DNA replication, inducing double-stranded DNA breakages, obstruction of RNA and protein synthesis and triggering apoptosis. Furthermore, this agent also stimulates degradation of topoisomerase I, likely mediated through ubiquitin-proteasomal pathway. Liposomal delivery of lurtotecan improves its penetration and delivery into tumors while lowering systemic side effects.
