The synthesis and mesomorphic properties of two series of compounds viz.(S)-(+)-4-(1-methylheptyloxy)phenyl 4′-(6″-alkoxypyridine-3-carbonyloxy)benzoates and (S)-(+)-l-methylheptyl4-[4′-(6″-alkoxypyridine-3-carbonyloxy)benzoyloxy]-benzoates are reported; the homologues of the former series exhibit smectic A and smectic C* phases while the derivatives of the latter series show rich polymesomorphism including the antiferroelectric phase. The mesophases have been characterised by using optical polarising microscopy and differential scanning calorimetric methods. Some physical properties such as the spontaneous polarisation, helical pitch, tilt angle and relative permittivity of two derivatives have also been investigated.

carboxylic acid of ligand is essential for binding via coordinate bond formation with Zn+2 ion in the enzyme active site. Moreover, the presence of a hydrophobic group, containing a hydrogen bond acceptor, at position 6 of the pyridine improves activity, e.g., 6-(hexyloxy) pyridine-3-carboxylic acid (Ki = 41.6 µM). Utilizing the weak esterase activity of CAIII, the inhibitory mode of 6-substituted nicotinic
