2,6-Bis(benzimidazol-2-yl)pyridine (BBP/CSFA-0) was identified in a CPE-based screening as a selective inhibitor of the in vitro bovine viral diarrhea virus (BVDV) replication. The EC50-values for the inhibition of BVDV-induced cytopathic (CPE) effect, viral RNA synthesis and the production of infectious virus were 0.3 ± 0.1 muM, 0.05 ± 0.01 muM and 0.3 ± 0.04 muM, respectively. Furthermore, BBP/CSFA-0 inhibits the in vitro replication of the classical swine fever virus (CSFV) with an EC 50 of 0.33 ± 0.25 muM. BBP/CSFA-0 proved in vitro inactive against the hepatitis C virus, that belongs like BVDV and CSFV to the family of Flaviviridae. Modification of the substituents on the two 1H-benzimidazole groups of BBP resulted in analogues equipotent in anti-BVDV activity (EC 50 = 0.7 ± 0.1 muM), devoid of cytotoxicity (S.I. = 142). BBP resistant BVDV was selected for and was found to carry the I261M mutation in the viral RNA-dependent RNA polymerase (RdRp). Likewise, BBP-resistant CSFV was selected for; this variant carries either an I261N or a P262A mutation in NS5B. Molecular modeling revealed that I261 and P262 are located in a small cavity near the fingertip domain of the pestivirus polymerase. BBP-resistant BVDV and CSFV proved to be cross-resistant to earlier reported pestivirus inhibitors (BPIP, AG110 and LZ37) that are known to target the same region of the RdRp. BBP did not inhibit the in vitro activity of recombinant BVDV RdRp but inhibited the activity of BVDV replication complexes (RCs). BBP interacts likely with the fingertip of the pestivirus RdRp at the same position as BPIP, AG110 and LZ37. This indicates that this region is a “hot spot” for inhibition of pestivirus replication.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 14220-64-5 is helpful to your research. Electric Literature of 14220-64-5

Carbon-nitrogen bond-forming cross-coupling reaction of haloarenes with N-trimethylsilyl (TMS)-substituted secondary and primary arylamines proceeded with the aid of a palladium catalyst and a fluoride activator. Various TMS-N(aryl)2, TMS-NH(aryl), and TMS-N(alkyl)2 reacted to give the corresponding coupled products in high yields. Multi-TMS-amine nucleophiles such as N,N-(TMS)2-aniline and N,N?-Ph2-N,N?-(TMS)2-p-phenylenediamine also participated in this C-N coupling to give multiply C-N coupled products in high yields. The novel C-N cross-coupling reaction was successfully applied to C-N bond-forming polymerization. Relative rates of the cross-coupling of p-bromotoluene with N-TMS-substituted primary and secondary amines showed that N-TMS-diphenylamine reacted faster than N-TMS-N-methylaniline or N-TMS-aniline, and N-TMS-morpholine was the least reactive, indicating that the low basicity of the nitrogen nucleophile is the key for the smooth coupling.

Removable tridentate directing groups inspired by pincer ligands have been designed to stabilize otherwise kinetically and thermodynamically disfavored 6-membered alkyl palladacycle intermediates. This family of directing groups enables regioselective remote hydrocarbofunctionalization of several synthetically useful alkene-containing substrate classes, including 4-pentenoic acids, allylic alcohols, homoallyl amines, and bis-homoallylamines, under Pd(II) catalysis. In conjunction with previous findings, we demonstrate regiodivergent hydrofunctionalization of 3-butenoic acid derivatives to afford either Markovnikov or anti-Markovnikov addition products depending on directing group choice. Preliminary mechanistic and computational data are presented to support the proposed catalytic cycle.

We report herein a facile approach to tetrahydropyridazines, a scaffold found in many natural products and biologically active entities, via Pd-catalyzed carboamination of readily available alkenyl hydrazones with aryl and alkenyl halides. Preliminary studies showed its promise for enantioselective synthesis. This work offers an expedient access to the tetrahydropyridazine scaffold bearing substitution patterns, thus significantly increasing the availability of these derivatives for downstream evaluation.

A new type of catalytic process to convert carboxylic acids and organoboron compounds into unsymmetrical ketones in one-pot under mild and neutral conditions was presented. The method allowed the use of an alpha, beta-unsatuarted carboxylic acids such as trans-cinnamic acid. Benzoic acid was converted into 1,3-diphenyl-2-propyn-1-one when it was treated with dimethyl dicarbonate and phenylacetylene in the presence of Pd(OAc)2 and PPh3. The catalytic coupling reaction was considered to proceed through oxidative addition of the mixed anhydride produced from benzoic acid and dimethyl dicarbonate to give the acylpalladium intermediate.

The enantioselective synthesis of a dimeric pyranonaphthoquinone closely related to the cardinalins is described. Whilst attempts to effect a double Hauser-Kraus annulation of enone 5 were unsuccessful using both bis-phthalide 4 and bis-sulfone 21, a single annulation of cyanophthalide 28 with enone 5 furnished functionalised naphthalene 31. Suzuki-Miyaura homocoupling of the aryl triflate 29 derived from 31 effected a late-stage construction of the biaryl bond and facilitated access to the biaryl 3. Double stereoselective lactol reduction installed the 1,3-cis stereochemistry of the pyran rings and a final double oxidative demethylation step furnished model dimer 1, completing the enantioselective synthesis of a dimeric pyranonaphthoquinone bearing the core structure of cardinalin 3.

(+)-Clusianone, an exo-type B PPAP with reported anti-HIV and chemoprotective activities, was synthesized in eleven steps with 97% ee starting from acetylacetone. An enantioselective decarboxylative Tsuji-Trost-allylation and a Ru-catalyzed ring-closing metathesis-decarboxylative allylation were used to control both diastereo- and enantioselectivity.
