  摘要：

  A series of water-soluble L-lysyl- and L-alanyl-amide prodrugs of the lipophilic antitumor 2-(4-aminophenyl)benzothiazoles has been synthesized to address formulation and bioavailability issues related to the desired parenteral administration of the chosen clinical candidate. The prodrugs exhibit the required pharmaceutical properties of good water solubility (in weak acid) and stability at ambient temperature and degradation to free base in vivo. The lysyl-amide of 2-(4-amino-3-methylphenyl)-5-fluorobenzothiazole (NSC 710305, 6d) has been selected for phase 1 clinical evaluation.

  A series of 2-arylbenzothiazole derivatives have been prepared as fluorogenic enzyme substrates in order to detect aminopeptidase, esterase, phosphatase and beta-galactosidase activity in clinically important Gram-negative and Gram-positive bacteria. Substrates were incorporated into an agar-based culture medium and this allowed growth of intensely fluorescent bacterial colonies based on hydrolysis by specific enzymes. Substrate 20 targeted L-alanine aminopeptidase activity and was hydrolysed exclusively by a range of Gram-negative bacteria and inhibited the growth of a range of Gram-positive bacteria. Substrate 19a targeted beta-alanyl aminopeptidase activity and generated fluorescent colonies of selected Gram-negative species including Pseudomonas aeruginosa. Substrate 21b targeted C8-esterase activity and resulted in strongly fluorescent colonies of selected species known to harbour such enzyme activity (e. g., Salmonella and Pseudomonas). Most Gram-negative species produced colonies with an intense blue fluorescence due to hydrolysis of phosphatase substrates 24a-c and substrate 24c was also hydrolysed by strains of Staphylococcus aureus. Compounds 26b and 26c targeted beta-galactosidase activity and generated strongly fluorescent colonies with coliform bacteria that produced this enzyme (e. g., Escherichia coli).
