The invention relates generally to macrocyclic compounds of formula I and their therapeutic use. More particularly, the invention relates to macrocyclic compounds that modulate the activity of IL-17 and/or are useful in the treatment of medical conditions, such as inflammatory diseases and other IL-17-associated disorders.
The present invention relates to compounds of Formula I, or pharmaceutically acceptable salts, esters, or prodrugs thereof: ( i ) which inhibit serine protease activity, particularly the activity of hepatitis C virus (HCV) NS3-NS4A protease. Consequently, the compounds of the present invention interfere with the life cycle of the hepatitis C virus and are also useful as antiviral agents. The present invention further relates to pharmaceutical compositions comprising the aforementioned compounds for administration to a subject suffering from HCV infection. The invention also relates to methods of treating an HCV infection in a subject by administering a pharmaceutical composition comprising a compound of the present invention.

a commercially available Co salt, a tetradentate phosphine ligand P(CH2CH2PPh2)3(PP3), and a base (denoted as [Co]/PP3/base), is developed for the methylation of C(sp3)–H and C(sp2)-H bonds using methanol as a methylating reagent. The Co(BF4)2·6H2O/PP3/K2CO3 catalytic system showed high catalytic activity for the methylation of C–H bonds in aryl alkyl ketones, aryl acetonitriles, and indoles, with wide
一种高效的钴基催化体系,由市售的钴盐,四齿膦配体P(CH 2 CH 2 PPh 2)3(PP 3)和碱(表示为[Co] / PP 3 / base)组成),用于使用甲醇作为甲基化试剂对C(sp 3)–H和C(sp 2)-H键进行甲基化。Co(BF 4)2 ·6H 2 O / PP 3 / K 2 CO 3催化体系对芳烷基酮,芳基乙腈和吲哚中CH键的甲基化反应具有很高的催化活性,具有广泛的底物范围和良好的官能团耐受性,在100°C条件下获得的甲基取代产物的收率好至极好C。这种便宜,容易获得且高效的Co基催化体系在使用甲醇的甲基化反应中可能具有广阔的应用前景。

Experimental and Computational Studies of Palladium-Catalyzed Spirocyclization via a Narasaka–Heck/C(sp<sup>3</sup> or sp<sup>2</sup>)–H Activation Cascade Reaction
es via a palladium-catalyzed tandem Narasaka–Heck/C(sp3 or sp2)–Hactivationreaction is reported here. The key step in this transformation is the activation of a δ-C–H bond via an in situ generated σ-alkyl-Pd(II) species to form a five-membered spiro-palladacycle intermediate. The concerted metalation-deprotonation (CMD) process, rate-determining step, and energy barrier of the entire reaction were
