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.

Photoisomerization of a series of substituted E-cinnamic acids in MeCN in their acid forms and as their corresponding protic ionic liquids (PILs) with light of 300 nm is studied. The nature, strength, number, and position effects of substituents on the photochemical behavior of E-cinnamic derivatives are investigated. The photosensitization of the reaction in the presence of Michler's ketone is also
