Synthesis of New Thiazole-Pyridine Hybrids and Their Anticancer Activity
摘要:
A series of new thiazole incorporated pyridine derivatives containing the phenoxyacetamide moiety as a linking bridge has been synthesized. The synthetic strategy involves condensation of 2-(4-formylphenoxy)-N-(thiazol-2-yl)acetamide with cyanoacetic hydrazide followed by heterocyclization with acetylacetone, treatment of the produced acrylamides with malononitrile and substituted acetophenones, then heating the generated chalcones with mononitrile in acetic acid and ammonium acetate. In vitro anticancer activity of the newly synthesized thiazole-pyridine hybrids has been evaluated against prostate (PC3), liver (HepG2), laryngeal (Hep-2), and breast (MCF-7) cancer cell lines. One of thiazole-pyridine compounds 8c demonstrates higher activity (IC50 5.71 mu M) against breast cancer than 5-fluorouracil used as a reference (IC50 6.14 mu M). Molecular docking procedure has provided valuable information on the binding sites of the synthesized compounds with rho-associated protein kinase 1 (ROCK-1).

coupling of the amino terminus of d-phenylalanine methylester to the free 5′-carboxylic acid moiety of 33 followed by sodium hydroxide treatment led to carboxylic acid analog 77. Hydrolysis of this material gave analog 78. The intermediate 77 served as the precursor for the preparation of novel dipeptidyl uridine analogs 79–99 through peptide coupling reactions to diverse amine reactants. None of the described

NIH Roadmap Initiative and the Pilot Scale Library (PSL) Program. Reaction core compounds contained -NH2 (2) and -COOH (44 and 93) groups that were coupled to a diversity of reactants in a parallel, solutionphase format to produce the target library. The assorted reactants included -NH2, -CHO, -SO2Cl, and -COOH functional groups, and condensation with the intermediate core materials 2 and 44 followed

The present invention is directed to a method for the synthesis of a bi-functional complex comprising a molecule part and an identifier oligonucleotide part identifying the molecule part. A part of the synthesis method according to the present invention is preferably conducted in one or more organic solvents when a nascent bi-functional complex comprising an optionally protected tag or oligonucleotide identifier is linked to a solid support, and another part of the synthesis method is preferably conducted under conditions suitable for enzymatic addition of an oligonucleotide tag to a nascent bi-functional complex in solution.

A library of eighty one adenosine antibiotic analogs was prepared under the Pilot Scale Library Program of the NIH Roadmap initiative from 5'-amino-5'-deoxy-2',3'-O-isopropylidene-adenosine 3. Diverse aldehyde, sulfonyl chloride and carboxylic acid reactant sets were condensed to 3, in solution-phase fashion, leading after acid-mediated hydrolysis to the targeted compounds in good yields and high purity. No marked antituberculosis or anticancer activity was noted on preliminary cellular testing, but these nucleoside analogs should be useful candidates for other types of biological activity.
