چکیده
A novel base-promoted cascade reaction of 2-methyl-3-(1-alkynyl)chromones to produce a 3C-xanthone-linked 3C-chromone scaffold has been developed. This tandem process involves multiple reactions such as Michael additions/cyclizations under mild conditions without a transition metal catalyst and inert atmosphere.

Background & Aim: Human parechovirus is a genus of picornaviruses which includes a number of important viruses of clinical significance. Recent sequence analysis suggests that human parechovirus type 1(HPEV-1) is distinct from other picornaviruses and lacks the motives believed to be involved in the protease function of 2A. The aim of this study was to analyse proteolytic activity of 3C pro...
متن کاملCoxsackievirus B3 protease 3C induces cell death in eukaryotic cells
Abstract: Coxsackievirus B3 (CVB3) is the most common agent known to cause viral myocarditis. The viral genome encodes a single polyprotein that is cleaved to produce several proteins by virally encoded proteases. Most of this proteolytic processing is catalyzed by a cysteine protease called 3C. The 3C protease plays major role in viral replication and cellular damage. To understand the mecha...
متن کامل3C- A Provably Secure Pseudorandom Function and Message Authentication Code.A New mode of operation for Cryptographic Hash Function
We propose a new cryptographic construction called 3C, which works as a pseudorandom function (PRF), message authentication code (MAC) and cryptographic hash function. The 3Cconstruction is obtained by modifying the Merkle-Damg̊ard iterated construction used to construct iterated hash functions. We assume that the compression functions of Merkle-Damg̊ard iterated construction realize a family of ...
متن کاملSynthesis of Titanium Carbide by the Combustion of TiO2-2Mg-C and 3TiO2-4Al-3C Systems in a Tubular Furnace
The combustion process of TiO2- 2Mg- C and 3TiO2-4Al-3C systems in a tubular furnace was investigated. TiC has been synthesized by the magnesiothermic reaction from a mixture of compacted powders of TiO2, Mg and charcoal as starting materials in the presence and absence of NaCl. The effects of temperature, pressure, and the stoichiometry ratio in the reactio...
متن کاملThe effects of F2 adsorption on NMR parameters of undoped and 3C-doped (8, 0) zigzag BPNTs
In this research, we studied the structure, properties and NMR parameters of interaction F2 gas with pristine and 3C-doped (8, 0) zigzag models of boron phosphide nanotubes (BPNTs). in order to reach these aims, we considered four different configurations for adsorption of F2gas on the outer and inner surfaces of BPNTs. The structures of all models were optimized by using density functional the...
