Copper-promoted sandmeyer difluoromethylthiolation of aryl and heteroaryl diazonium salts

An efficient copper-promoted difluoromethylthiolation of aryl and heteroaryl diazonium salts is described. The reaction is conducted under mild reaction conditions and various functional groups were compatible. In addition, reactions of heteroaryl diazonium salts such as pyridyl, quinolinyl, benzothiazolyl, thiophenyl, carbazolyl, and pyrazolyl diazonium salts occurred smoothly to afford the medicinally important difluoromethylthiolated heteroarenes. Furthermore, a more practical one-pot direct diazotization and difluoromethylthiolation protocol was developed, and it converts the aniline derivatives into difluoromethylthiolated arenes. The utility of the method is demonstrated by difluoromethylthiolation of a number of natural products and drug molecules. A dose of salt: The title reaction is conducted under mild reaction conditions and various functional groups are compatible. (Hetero)aryl diazonium salts reacted smoothly to afford the medicinally important difluoromethylthiolated (hetero)arenes. A practical one-pot direct diazotization and difluoromethylthiolation protocol was developed for aniline derivatives to generate difluoromethylthiolated arenes.

Discovery of novel guanidinophenylpyrazole human acrosin inhibitors by molecular hybridization

Human acrosin is a promising target for male contraceptives. A series of novel guanidinophenylpyrazole derivatives were rationally designed by molecular hybridization of the phenylpyrazole and guanidinobenzoate inhibitors. Most of the target compounds showed potent human acrosin inhibitory activities. In particular, compound F3 was a highly active human acrosin inhibitor (IC50 = 1.26 muM) with good selectivity over trypsin. Molecular docking studies revealed that compound F3 formed hydrophobic and hydrogen bonding interactions with the active site of human acrosin. Compound F3 represents a promising lead compound for the development of novel male contraceptives.

Near-Infrared Photoswitching of Azobenzenes under Physiological Conditions

Biological tissue exhibits an absorbance minimum in the near-infrared between 700 and 900 nm that permits deep penetration of light. Molecules that undergo photoisomerization in this bio-optical window are highly desirable as core structures for the development of photopharmaceuticals and as components of chemical-biological tools. We report the systematic design, synthesis, and testing of an azobenzene derivative tailored to undergo single-photon photoswitching with near-infrared light under physiological conditions. A fused dioxane ring and a methoxy substituent were used to place oxygen atoms in all four ortho positions, as well as two meta positions, relative to the azobenzene N=N double bond. This substitution pattern, together with a para pyrrolidine group, raises the pKa of the molecule so that it is protonated at physiological pH and absorbs at wavelengths >700 nm. This azobenzene derivative, termed DOM-azo, is stable for months in neutral aqueous solutions, undergoes trans-to-cis photoswitching with 720 nm light, and thermally reverts to the stable trans isomer with a half-life near 1 s.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Design, synthesis and evaluation of pyrazole bearing alpha-aminophosphonate derivatives as potential acetylcholinesterase inhibitors against Alzheimer’s disease

A series of novel scaffold of N-substituted pyrazole derived alpha-aminophosphonates were designed, synthesized and evaluated for their anti-cholinesterase activity. Porcine pancreatic lipase (PPL) was used as a catalyst for the organic transformation. Compounds 4ah and 4bh proved to be more potent than the standard drug tacrine, rivastigmine and galantamine for AChE inhibition activity with IC50 value between 0.055 ¡À 0.143 muM and 0.017 ¡À 0.02 muM respectively. BuChE activity of the synthesized derivatives possessed moderate to weak inhibition potency. 4bh shows a comparable activity to Rivastigmine against BuChE (IC50 = 6.331 ¡À 0.17). The compounds did not show any cytotoxicity against HEK-293 cells when compared to standard drugs. Cell viability assay using N2a cell showed compounds 4ah and 4bh showed comparable results to positive control rivastigmine. In addition, these compounds showed promising antioxidant activities against DPPH and H2O2 scavenging. Both 4ah and 4bh showed mixed-type inhibition which supported by molecular docking studies by acting as a dual site inhibitor. The predicted ADME showed good pharmacokinetics as predicted by QikProp. DNA cleavage studies and DNA protection assay of active compounds were also performed. 4bh did not show any damage to DNA and was protective in nature.

A two-step, three-component queuing cascade leading to dihydrobenzoxepine and dihydrobenzazepine derivatives

A palladium-catalyzed reaction of methylenespiropentane (11) with iodobenzene (12) under typical Heck conditions [Pd(OAc)2, PPh 3, Et3N, DMF] produced a mixture of the unstable [3]dendralene 13 and allylidenecyclopropane 14 in 38 % yield. When an analogous reaction with iodobenzene was carried out in the presence of morpholine (25) and of tris(2-furyl)phosphane (TFP) instead of triphenylphosphane, the dienes 26, 28 and 31 were generated by nucleophilic trapping of pi-allylpalladium intermediates 30 and 32. The cross coupling of methylenespiropentane (11) with the functionalized aryl iodides 33a-g in the presence of a palladium precatalyst [Pd(OAc)2, TFP, Et3N, DMF] at 80C, 3 h, provided the seven-membered 3,4-dimethylene-substituted heterocycles 34a-g and 35b which, upon addition of dimethyl fumarate (19), underwent Diels-Alder reactions to furnish bicyclic and higher oligocyclic dihydrobenzoxepine and -benzazepine derivatives 36a-g and 37b, yet in rather moderate yields of 18-29% only. The overall process constitutes a one-pot, two-step, three-component queuing cascade. Wiley-VCH Verlag GmbH & Co. KGaA, 2007.

Synthesis, molecular modeling, and biological evaluation of novel 1, 3-diphenyl-2-propen-1-one based pyrazolines as anti-inflammatory agents

A novel series of 1,3-diphenyl-2-propen-1-one (chalcone) derivatives was synthesized by a simple, eco-friendly, and efficient Claisen-Schmidt condensation reaction and used as precursors for the synthesis of new pyrazoline derivatives. All the synthesized compounds were screened for anti-inflammatory related activities such as inhibition of phospholipase A2 (PLA2), cyclooxygenases (COX-1 and COX-2), IL-6, and TNF-alpha. The results of the above studies show that the compounds synthesized are effective inhibitors of above pro-inflammatory enzymes and cytokines. Overall, the results of the studies reveal that the pyrazolines with chlorophenyl substitution (1b-6b) seem to be important for inhibition of enzymes and cytokines. Molecular docking experiments were performed to clarify the molecular aspects of the observed COX-inhibitory activities of the investigated compounds.

Efficient and Practical Transfer Hydrogenation of Ketones Catalyzed by a Simple Bidentate Mn?NHC Complex

Catalytic reductions of carbonyl-containing compounds are highly important for the safe, sustainable, and economical production of alcohols. Herein, we report on the efficient transfer hydrogenation of ketones catalyzed by a highly potent Mn(I)?NHC complex. Mn?NHC 1 is practical at metal concentrations as low as 75 ppm, thus approaching loadings more conventionally reserved for noble metal based systems. With these low Mn concentrations, catalyst deactivation is found to be highly temperature dependent and becomes especially prominent at increased reaction temperature. Ultimately, understanding of deactivation pathways could help close the activity/stability-gap with Ru and Ir catalysts towards the practical implementation of sustainable earth-abundant Mn-complexes.
