New series of benzimidazole ring core conjugated with either dithiocarbamate or thiopropyl linkers, hybridized with different secondary amines were synthesized; 5–15 and 22–31; respectively. The new compounds were characterized by different spectroscopic techniques (1H, 13C 1D & 2D NMR, ESI-MS and IR). They were screened for in vitro anticancer activity against breast cancer using MCF7 cell line. The results obtained revealed that compounds 5, 12, 15 and 25 were the most active among the synthesized series exhibiting IC50 15N-labeled Pin1 enzyme was conducted using state-of-the-art 2D NMR binding experiments. Results showed promising binding between compounds 5, 12, and 25 by chemical shift perturbation (peak shifting or peak disappearance). Molecular docking study were quite valuable to explain the binding mode of active derivatives via hydrogen bonding. Additional contact preferences and surface mapping studies stated the similarity pattern between active candidates which may pave the way for more precise anti breast cancer target optimization.

The synthesis of unprecedented benzimidazole-fused thiazocines, thiazonines, and thiazecines having an exocyclic double bond is reported. The process proceeds through an 8-, 9-, or 10-exo-dig cyclocarbopalladation followed by reduction. The scope and limitations were established and showed the importance of the precursor structure for the success of the reaction. A competition between the exo-dig and the endo-dig cyclization was observed for two substrates bearing an N-homopropargyl chain, the endo-cyclization leading to rarely encountered 10- and 11-membered N,S-heterocycles with a trans-endocyclic double bond. X-ray structures of three products were obtained by co-crystallization with fumaric acid and show the twisted structures of these molecules.

Substituted 1H-benzimidazoles, pyrazolones, and pyrazoles have been synthesized by the condensation of ortho-phenylenediamines and phenylhydrazines, respectively, with ethyl 4-chloro-3-oxobutanoate in good yields. The present approach is novel, straightforward, and being reported for the first time with ethyl 4-chloro-3-oxobutanoate.

(Chemical Equation Presented) A team of three: 2-Aminoimidazole, triazole, and tether units together resulted in conjugates (see picture, n=4-6 for the most active compounds) that are capable of inhibiting and dispersing bacteria biofilms without inducing bacterial death. Such biofilms have been implicated in a plethora of medical problems, including infection of implanted medical devices and the mortality of cystic fibrosis patients.

This invention relates to a novel class of heterocyclic compounds that bind chemokine receptors, inhibiting the binding of their natural ligands thereby. These compounds result in protective effects against infection by HIV through binding to chemokine receptors, including CXCR4 and CCR5, thus inhibiting the subsequent binding by these chemokines. The present invention provides a compound of Formula I wherein, W is a nitrogen atom and Y is absent or, W is a carbon atom and Y═H; R1to R7may be the same or different and are independently selected from hydrogen or straight, branched or cyclic C1-6alkyl; R8is a substituted heterocyclic group or a substituted aromatic group Ar is an aromatic or heteroaromatic ring each optionally substituted at single or multiple, non-linking positions with electron-donating or withdrawing groups; n and n′ are independently, 0-2; X is a group of the formula: Wherein, Ring A is an optionally substituted, saturated or unsaturated 5 or 6-membered ring, and P is an optionally substituted carbon atom, an optionally substituted nitrogen atom, sulfur or oxygen atom. Ring B is an optionally substituted 5 to 7-membered ring. Ring A and Ring B in the above formula can be connected to the group W from any position via the group V, wherein V is a chemical bond, a (CH2)n″group (where n″=0-2) or a C═O group. Z is, (1) a hydrogen atom, (2) an optionally substituted C1-6alkyl group, (3) a C0-6alkyl group substituted with an optionally substituted aromatic or heterocyclic group, (4) an optionally substituted C0-6alkylamino or C3-7cycloalkylamino group, (5) an optionally substituted carbonyl group or sulfonyl.
