Synthesis and evaluation of druglike parameters via in silico techniques for a series of heterocyclic monosquarate-amide derivatives as potential carboxylic acid bioisosteres.

Herein, we present a synthetic compound library comprising of 13 structurally diverse heterocyclic monosquarate-amide derivatives. The compounds featured in this library were designed as potential bioisosteric replacements carboxylic acid moiety's. A good selection of the compounds presented exhibit unique molecular architecture and have shown promising results following in silico evaluation of 'druglike properties' using Swiss ADME. The research presented in this work focuses on the preparation of derivatives of 3,4-dihydroxycyclobut-3-ene-1,2-dione, a known carboxylic acid bioisostere.
