diamino acid/neoplasms

The in vitro cytotoxicity and differential cellular sensitivity of a series of new N-methyl and N-propargyl urea and nitrosourea derivatives of diamino acids were determined in the National Cancer Institute's primary antitumor drug screen. These compounds have a level of cytotoxic activity

A method for targeted delivery of the cytotoxic agent 5-fluorodeoxyuridine (FudR) (1) to sites of metastatic prostate cancer is described. The prodrug was synthesized by coupling the active drug (FudR) to the PSA-peptide via a self-cleaving diamino acid linker to produce HSSKLQ-Leu-Aib-FudR. This

The in vitro cytotoxicity and differential cellular sensitivity of a series of new N1-methyl, N1-allyl, N1-2-chloroethyl and N1-propargyl nitrosourea derivatives of diamino acids were determined in the National Cancer Institute's primary antitumor drug screen. The compounds tested showed an in vitro

Immunological response related to photodynamic therapy (PDT) is one of the basic elements that influence on the efficiency of this cancer treatment method. Diamino acid derivatives of protoporphyrin IX are promising photosensitizing agents that are intended to be the components of new anti-tumor

The synthesis and evaluation of some 2'- and 7-amino acid derivatives of taxol (1) are reported. Reaction of taxol with N-protected amino acids gave 2'-N-protected amino acid esters of taxol. However, deprotection of the amino group and subsequent isolation of products were complex and only
