Alzheimer disease is multi-factorial and inflammation plays a major role in the disease progression and severity. Metals and reactive oxygen species (ROS) are the key mediators for inflammatory conditions associated with Alzheimer's. Along multi-factorial nature, major challenge for developing new drug is the ability of the molecule to cross blood brain barrier (BBB). We have designed and synthesized multi-target directed hexafluorocarbinol containing triazoles to inhibit Amyloid β aggregation and simultaneously chelate the excess metals present in the extracellular space and scavenge the ROS thus reduce the inflammatory condition. From the screened compound library, compound 1c found to be potent and safe. It has demonstrated inhibition of Amyloid β aggregation (IC50 of 4.6 μM) through selective binding with Amyloid β at the nucleation site (evidenced from the molecular docking). It also chelate metals (Cu+2, Zn+2 and Fe+3) and scavenges ROS significantly. Due to the presence of hexafluorocarbinol moiety in the molecule it may assist to permeate BBB and improve the pharmacokinetic properties. The in-vitro results of compound 1c indicate the promiscuity for the development of hexafluorocarbinol containing triazoles amide scaffold as multi-target directed therapy against Alzheimer disease.

A new family of Ru (III) complexes has been synthesized, characterized and their catalytic performance has been tested for alkyne–azide cycloaddition (AAC) in water under ultrasonic irradiation conditions. These complexes are found to be effective heterog
Alkyl Propiolates Participated [3+2] Annulation for the Switchable Synthesis of 1,5- and 1,4-Disubstituted 1,2,3-Triazoles Containing Ester Side Chain

By means of a featured enamine activation, the alkyl propiolates have been successfully employed in the [3+2] annulation for the synthesis of 1,2,3-triazoles. The synthesis of both 1,4- as well as the hardly available 1,5-disubstituted 1,2,3-triazoles can be selectively accessed by using tosyl azide and tosyl hydrazine as nitrogen source, respectively.

Copper Acetate Catalyzed Regio-selective Synthesis of Substituted 1,2,3-Triazoles: A Versatile Azide–Alk-ene Cycloaddition/Oxidation Approach
Rohilla, Sandeep,Patel, Shyam Sunder,Jain, Nidhi
, p. 847 - 854 (2017/01/18)
A copper acetate catalyzed oxidative cycloaddition reaction of benzyl and aryl azides with terminal and internal olefins that contain electron-withdrawing groups (COOR, CONH2, CN, CHO, COR) has been developed. The reaction employs air as the oxidant and does not require any base or additives to afford 1,4-disubstituted and 1,4,5-trisubstituted 1,2,3-triazoles in good to excellent yields with high regioselectivity.

A reaction between two equivalents of bulky thiourea, i.e., 1,3-bis(2,6-dimethylphenyl)thiourea (L) [L = (ArNH)2C = S; Ar = 2,6-Me2C6H3], and CuCl2 or CuCl in THF solvent afforded a bulky thiourea-sta

The use of the positron emitter nitrogen-13 (13N) has been historically restricted due to its short half-life (T1/2 = 9.97 min). However, its stable isotopes (nitrogen-14 and nitrogen-15) are present in many biologically active molec

Polymer stabilized monovalent copper has been synthesized using an in situ chemical transformation route and was characterized by means of different microscopic, optical and surface characterization techniques, which offered information about the chemical structure of the polymer and the morphology of the complex. The supramolecular material, Cu(i)-poly(2-aminobenzoic acid), denoted Cu(i)-pABA, showed catalytic activity for the cycloaddition reaction between terminal alkynes and azides to synthesize 1,2,3-triazoles with excellent yields. The catalyst was recovered from the reaction mixture and recycled several times without an appreciable loss of catalytic activity. The whole strategy was done under ambient conditions and in the presence of water as a solvent.
