Bisthioureas of pimelic acid and 4-methylsalicylic acid derivatives as selective inhibitors of tissue-nonspecific alkaline phosphatase (TNAP) and intestinal alkaline phosphatase (IAP): Synthesis and molecular docking studies

Alkaline phosphatases (ALPs) are membrane bound metalloenzymes, distributed all over the body. Recent studies have revealed that by targeting ALPs can lead towards the treatment of many deadliest diseases including cardiac, cancerous and brain diseases. Thioureas and their derivatives are of considerable significance and are privileged scaffolds in medicinal chemistry. They show a wide range of pharmacological activities such as an-tibacterial, antiparasitic, anti-inflammatory and antioxidants etc. On the other hand, salicylic acid and its de-rivatives are known for its broad spectrum of activities. The work presented comprises of synthesis of N-acyl-N’- aryl substituted bisthioureas of pimelic acid (1-7) and 3,5-dimethyl pyrazole (11), 1-aroyl-3-aryl thiourea (12) and 1,3,4-oxadiazole (13) derivatives of 4-methyl salicylic acid. Structures of all the synthesized compounds were characterized by FT-IR and H-1 NMR spectroscopic analysis. Synthesized compounds were evaluated for their alkaline phosphatases inhibition potential and exhibited high potency as well as selectivity towards h-TNAP and h-IAP. Compound 7 and 12 which were the bisthiourea derivative of pimmelic acid and thiourea derivative of 4-methyl salicylic acid, respectively, showed excellent selectivity against h-TNAP and h-IAP, respectively.

Highly sensitive ruthenium complex-based fluorescent probe for copper ion detection

A Ru(II) complex 1 ([Ru(bpy)(2)(L)](PF6)(2) (L = 2-(1H-pyrazol-5-yl)-1H-imidazo-[4,5-f] [1,10] phenanthroline, bpy = 2,2′-bipyridine)), which included adjacent imidazole and pyrazole moieties as responsive bidentate ligand, had been designed and synthesized as a ‘turn-off fluorescent probe for sensitively and selectively detecting Cu2+ in methanol and test strips. It displayed easy synthesis, large Stokes shift (178 nm) and long emission wavelength (633 nm). After addition of Cu2+, the probe 1 exhibited obvious fluorescence quenching (ca. 83%) and color change from red to dark. The detection limit of Cu2+ ions was as low as 1.78 x 10(-8) M, which was far lower than the permissible level of copper ion (similar to 20 mu M) in drinking water set by the EPA (Environmental Protection Agency). Moreover, the results of test strip experiments and real water sample detection experiments demonstrated the probe 1 possesses potential application of ions recognition in environment.
