Pyridazine derivative showed much diversified activity. Previously 77 pyridazine derivatives were synthesized and evaluated the antihypertensive property. Pyridazine derivatives also showed antitumor and antiproliferative behavior. By kept this idea in mind we repurposed those pyridazine derivatives towards antiproliferation using in silico, and in vitro methods. Molecular docking analysis of pyridazine derivatives against DNA (PDB id: 6BNA) were performed and top4 molecules (R45, R60, R67, R70) were identified based on their docking scores.

The preparation and physico-chemical characteristics of zinc(II) porphyrin and phthalocyanine derivatives with biphenyl units are reported. These compounds have been prepared as components for molecular electronics systems and rotor-based molecular machines, where the biphenyl units can act as paddles because they are oriented quasi-perpendicularly to the plane of the aromatic macrocycles which would be coordianted through the transition metal ion by an axial ligand. The minimalist design along with the absence of solubilizing groups leads to a low solubility of the compounds in organic solven

The Friedel-Crafts acylation of 2-(biphenyl-4-yl)-5-phenyl-1,3,4-oxadiazole (PBD) with hippuryl chloride has been used to prepare the derivative V which on cyclization with POCl3 or P4S10 gives the respective oxazole (or thiazole) derivative of PBD, XIa or XIb. The reaction of carboxylic acid II with 4-(o-aminoacetyl)biphenyl in the presence of CDI gives N-acyl-α-aminoketone VII; the analogous compound VI has been prepared by acylating of o-aminoacetophenone with acyl chloride III. The cyclization of these compounds gives bifluorophores Xa - Xd.

The metal-to-ligand charge transfer (MLCT) bands which occur at ~440 nm are transitions from d orbitals on the platinum metal center to * orbitals of the diimine ligands.

Currently one of the biggest problems for PLED as commercially viable displays is the low quantum efficiency. Most PPV-related polymers can be easily p-doped, so the mobility of holes is usually much greater than that of electrons, which may result in imbalance of electron- and hole-injection that leads to low EL efficiency. This problem is usually solved by device engineering, or development of highly effi

Abstract Methadone is a synthetic opioid agonist that was developed over 50 years ago. It is a biphenyl propylamine synthetic potent mu and delta agonist. The chemical structure is distinctly different from other opioid alkaloids or theobaine derivatives. Methadone’s physicochemical properties, pharmacodynamics and kinetics are unique compared with hydrophilic opioids. In addition methadone is not a pure mu opioid receptor (MOR) agonist, which adds complexity to the determination of opioid equianalgesia. Finally, as evidenced by clinical experience, there is a large interindividual difference
