Synthesis and mesomorphic properties of 2,4-bis(4′-n-pentyloxybenzoyloxy)- benzylidine-4″- n-alkoxyaniline
摘要:
The synthesis andmesomorphic properties of a new series of 2,4-bis(4'-n-pentyloxybenzoyloxy)- benzylidine-4 ''-n-alkoxyaniline (DC5An) are reported. The molecular structure of compounds was confirmed by FTIR, H-1-NMR, C-13-NMR, mass spectroscopy and elemental analysis. The mesomorphic properties were studied by differential scanning calorimetry (DSC) and polarizing optical microscopy (POM) measurements. All compounds of the series exhibit nematic (N) and smectic C (SmC) phases. The first four homologues (DC5A1-DC5A4) display a N mesophase, whereas the highest homologues (DC5A5-DC5A10) exhibit an enantiotropic dimorphism N and SmC phases. The mesomorphic properties of the present series are compared and discussed with other structurally related series.

new homologous series of compounds with a heterocyclicring having sulfur and oxygen as a hetero atom derived from p-hydroxy acetophenone and alkoxy aniline containing cinnamate-azomethine as central linkages have been synthesized. viz. 4(furalacryloxy) α-methyl benzylidine-4′-alkoxy aniline and 4(thianylacryloxy) α-methyl benzylidine-4′-alkoxy aniline. The compound of both the series have been characterized

The present invention particularly relates to novel nitrate esters of paracetamol. The nitrate esters of paracetamol are prepared by reacting the paracetamol with dihaloalkyl compound and followed by reaction with silver nitrate to obtain the corresponding nitrate ester derivatives. The nitrate esters of paracetamol are useful as analgesic, anti-inflammatory agents.
The present invention provides hepatoprotectant acetaminophen mutual prodrugs, which have an acetaminophen moiety covalently linked to a second moiety that may act as a hepatoprotectant against acetaminophen hepatotoxicity. Additionally, acetaminophen mutual prodrugs may have improved water solubility which may provide better suitability for parenteral and other dosage forms relative to administration of acetaminophen. Also provided are methods of treating a disease or condition that is responsive to acetaminophen (such as fever, pain and ischemic injury) using hepatoprotectant acetaminophen mutual prodrugs, as well as kits and unit dosages.
