Purpose: To study the enzyme inhibition activity of various sulfonamides derived from dagenan chloride. Methods: The synthesis of N-(naphthalen-1-yl)-4-acetamidobenzenesulfonamide (3) was carried out by gearing up 1-naphthylamine (1) with dagenan chloride (2) in water in the presence of Na2CO3 solution. Further, compound 3 was treated with various alkyl/aralkyl halides (4a-o) to yield 5a-o in a...

Dihydrofolate reductase (DHFR) is an important enzyme for de novo synthesis of nucleotides in Plasmodium falciparum and it is essential for cell proliferation. DHFR is a well known antimalarial target for drugs like cycloguanil and pyrimethamine which target its inhibition for their pharmacological actions. However, the clinical efficacies of these antimalarial drugs have been compromising due ...
