(E)‐1‐heteroaryl‐3‐arylpropen‐1‐ones. The 13C chemicalshift values (δC) of the chalcone derivatives were determined in order to find if they correlated with the Hammett σ values. A good correlation, especially for the β‐C for both series, was found for the 13C chemicalshift values (δC) of the chalcone derivatives with the Hammett σ values. The chemicalshift values of the β‐C of the heterocyclic compounds

Inhibitors of CYP1 enzymes may play vital roles in the prevention of cancer and overcoming chemo-resistance to anticancer drugs. In this letter, we report synthesis of twenty-three pyrrole based heterocyclic chalcones which were screened for inhibition of CYP1 isoforms. Compound 3n potently inhibited CYP1B1 with an IC50 of ∼0.2 μM in Sacchrosomes™ and CYP1B1-expressing live human cells. However, compound

A series of newly synthesized potent bioactive 2-pyrrolyl styryl ketone derivatives were characterized by spectral techniques. The effect of substituent on the absorption maximum, IR stretching frequencies and NMR chemical shifts were investigated. DFT calculations were made to calculate HOMO–LUMO energies and natural bond orbital analysis [NBO]. The electric dipole moment (μ) and the hyperpolarisability

25, and 26 showed promising anticancer activity in all four tested cancer cell lines (HL-60, MOLT-4, PC-3, and HeLa). Compound 25 emerged as a very good potentiator of ciprofloxacin against multidrug resistant S. aureus and also showed promising anticancer activity. The present communication describes syntheses, bio-evaluation, and structure-related activity of the (E)-3-(substitutedphenyl)-1-hetrylprop-2-en-1-ones

anti-inflammatory agents, twenty-four chalcone derivatives including seven new compounds (13 - 17, 21 and 23) containing pyrrole moiety were designed, synthesized, and assessed for their nitric oxide (NO) and prostaglandin E2 (PGE2) suppression ability on IFN-γ/LPS-induced RAW 264.7 macrophage cells. Results showed that none of the synthesized compounds were PAINS-associated molecules, with 3-(2,5-dimethoxyphenyl
