Heterocyclic Derivatives of 4-Amino-1,5-dimethyl-2-phenyl-1,2-dihydro-3H-pyrazol-3-one
摘要:
A convenient and scalable preparative method for the synthesis of azomethines from 4-amino-1,5-dimethyl-2-phenyl-1,2-dihydro-3H-pyrazol-3-one and substituted benzaldehydes, as well as 1,2-oxazole and 1,2-thiazolecarbaldehyde was developed.

The present invention discloses (1) phenolic ester hybrids of niacin with m-methoxy-p-hydroxy phenyl compounds like eugenol, vanillin, apocynin, ferulic acid, isoferulic acid and eugenol epoxide and (2) cocrystals of hybrids as above, particularly cocrystal of niacin-eugenol hybrid with cocrystal former like eugenol and oxalic acid (3) novel pharmaceutical compositions comprising a combination of niacin and one or more small molecule/potentiating agent like eugenol, curcumin, cinnamic acid, meclofenamic acid, and their use in the treatment of a disorder or a disease caused by excess production of amyloid beta peptide-42 (Aβ42), its deposition, accumulation, and plaque formation including Alzheimer's Disease, dementia and mild cognitive impairment as well as other neurodegenerative diseases such as Parkinson's Disease and ischemic stroke.

A convenientone-pot approach was proposed for the synthesis of new derivatives of 8,9,10,12tetrahydrobenzo[a]acridin-11(7H)-one and 10,12-dihydrobenzo[f]pyrimido[4,5-b]quinoline-9,11(7H,8H)-dione containing residues of nicotinic and isonicotinic acids covalently attached via ester groups in different positions of the aromatic core. Quaternary ammonium salts of the synthesized acridine derivatives
