Trimelamol
Trimelamol (CB10-375; NSC283162) is a highly efficient acid-catalyzed DNA interstrand crosslinker with low neurotoxicity due to its limited BBB penetration. Trimelamol exhibits anti-tumor activity and overcomes platinum resistance. Trimelamol is investigated for lung and ovarian cancer research[1][2][3][4][5].

Trimelamol exerts its cytotoxicity directly through its N-hydroxymethyl group, and the toxicity is irreversible after the drug is removed. It has a faster onset of action than HMM and PMM[1][2].
Trimelamol (0.5-500 μM, 1 h) cross-linking is its main anti-tumor mechanism. In 32P-end-labelled pBR322 plasmid DNA, it significantly cross-links DNA at concentrations ≥ 2.5 μM, and the cross-linking efficiency is higher under acidic conditions[3].
Trimelamol has a broad spectrum of cytotoxicity and is effective against platinum-resistant ovarian cancer cells (IC50 range: 8.5-55.4 μM)[4].

Trimelamol (15-60 mg/kg, i.p., once a day for 5 days, 4 consecutive weeks) is effective against platinum-sensitive/resistant ovarian cancer and hormone-dependent breast cancer in xenograft model mice, especially in the acquired resistance model[4].
Trimelamol (7.5-60 mg/kg, i.p, once a day for 5 days, 3 consecutive weeks) administered parenterally was significantly effective in BALB/c female mice bearing subcutaneous T-61/MX-1 tumors and less active in BALB/c female mice bearing subcutaneous Br-10 tumors. It exhibited moderate toxicity at high doses, but manageable toxicity at low concentrations[5].

Animal Model:(PXN/65, HX110, HX110P, HX62, T-61) xenograft tumor model in nude mice[4]
-
Dosage:15 mg/kg, 30 mg/kg, 60 mg/kg for PXN/65, HX110, HX110P, HX62; 15 mg/kg for T-61
-
Administration:Intraperitoneal injection (i.p.), once a day for 5 days, 4 consecutive weeks
-
Result:had curative activity against PXN/65, HX110, HX110P, and T-61, but HX62 was non-curative but had a better T/C value (0.20) than cisplatin (0.40–0.84).

Dosage:60 mg/kg, 30 mg/kg, 15 mg/kg, 7.5 mg/kg for T-61, MX-1; 60 mg/kg for Br-10, R-27, MCF-7
-
Administration:Intraperitoneal injection (i.p.), once a day for 5 days, 3 consecutive weeks
-
Result:Completely regressed tumors in the T-61 model at 60 mg/kg. Significantly reduced tumor weight at 30 mg/kg (T/C = 3.8%).
Completely regressed tumors in the MX-1 model at both 60 and 30 mg/kg. Reduced tumor weight at 15 mg/kg (T/C = 8.3%).
Exhibited marginal activity in the Br-10 model at 60 mg/kg (T/C = 48.2%). Was insensitive in the R-27 and MCF-7 tumor models.
