Palladium-catalyzed c-4 selective coupling of 2,4-dichloropyridines and synthesis of pyridine-based dyes for live-cell imaging

An alternative process of Pd-catalyzed C-4 selective coupling of 2,4-dichloropyridines with boronic esters was developed, which afforded 24 examples of C-4 coupled pyridines in moderate to good yields. After further arylation, 21 examples of C-2, C-4 diarylated pyridines with a significant photophysical property were obtained, which were applied as pyridine-based dyes into live-cell imaging with good biocompatibility and low toxicity.

Discovery of a COX-2 selective inhibitor hit with anti-inflammatory activity and gastric ulcer protective effect

Aim: A novel series of 2-arylimino-5-arylidenethiazolidin-4-ones 12a-n were synthesized and all the target compounds were fully characterized by IR, 1H NMR, 13C NMR, mass spectroscopy and elemental analysis. Materials & methods: All the target compounds were evaluated for their COX inhibition by enzyme immunoassay kit and in vivo anti-inflammatory activity. Results: Tested compounds were found more potent inhibitors of COX-2 (IC50 = 0.54-3.14 M) than COX-1 (IC50 = 4.97-11.52 M). The ulcerogenic liability of compounds 12(d, e, f, h, k, m) was performed and showed gastric safety more than or comparable to celecoxib. Conclusion: In addition, docking study of the most potent and selective compound 12h into COX-2 active site revealed that this target compound assumed interactions and binding pattern similar to that of as a cocrystallized ligand bromocelecoxib (S-58).

Synthesis, characterization and antimicrobial evaluation of novel quinoline based 2-azetidinones and 4-thiazolidinones

The present work describes the synthesis of a series of quinoline based 4-thiazolidinone and 2-azetidinone derivatives from Schiff bases obtained from the condensation of 2-chloro-3-formylquinoline and 3-4-aminoacetophenones. Quinoline based 4-thiazolidinone and 2-azetidinone derivatives have been prepared by the reaction of various substituted Schiff base with thioglycholic acid and chloroacetyl chloride, respectively. The intermediate Schiff bases were synthesized by the condensation of different quinoline aldehydes with amino acetophenones. The starting compound i.e aldehyde was synthesized through Vilsmeier reaction from respective acetanilides. The synthesized compounds were characterized by their physical and spectral data. The synthesized compounds were screened for their antibacterial and antifungal activities by using cup plate method against Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa, 25, 50, 100 mug/mL concentration using ciprofloxacin as reference standard drug and Aspergillus Niger, Candida albicans as same concentration using clotrimazole as reference drug, respectively. The spectral data of synthesized compounds of (3a-f), (4a-e) and (5a-f) were characterized by ES Mass, 1H-NMR, IR spectrophotometric methods. The antimicrobial results revealed that the quinoline based Schiff bases, azitidinone and thiazolodinones analogues showed good activity towards Gram (+) bacteria as compared to ciprofloxacin. These compounds showed decent activity against Gram (-) bacteria.

Development of a novel sulfonate ester-based prodrug strategy

A self-immolative gamma-aminopropylsulfonate linker was investigated for use in the development of prodrugs that are reactive to various chemical or biological stimuli. To demonstrate their utility, a leucine-conjugated prodrug of 5-chloroquinolin-8-ol (5-Cl-8-HQ), which is a potent inhibitor against aminopeptidase from Aeromonas proteolytica (AAP), was synthesized. The sulfonate prodrug was considerably stable under physiological conditions, with only enzyme-mediated hydrolysis of leucine triggering the subsequent intramolecular cyclization to simultaneously release 5-Cl-8-HQ and form gamma-sultam. It was also confirmed that this gamma-aminopropylsulfonate linker was applicable for prodrugs of not only 8-HQ derivatives but also other drugs bearing a phenolic hydroxy group.

Organocatalytic, diastereo- and enantioselective synthesis of nonsymmetric cis -stilbene diamines: A platform for the preparation of single-enantiomer cis -imidazolines for protein-protein inhibition

The finding by scientists at Hoffmann-La Roche that cis-imidazolines could disrupt the protein-protein interaction between p53 and MDM2, thereby inducing apoptosis in cancer cells, raised considerable interest in this scaffold over the past decade. Initial routes to these small molecules (i.e., Nutlin-3) provided only the racemic form, with enantiomers being enriched by chromatographic separation using high-pressure liquid chromatography (HPLC) and a chiral stationary phase. Reported here is the first application of an enantioselective aza-Henry approach to nonsymmetric cis-stilbene diamines and cis-imidazolines. Two novel mono(amidine) organocatalysts (MAM) were discovered to provide high levels of enantioselection (>95% ee) across a broad range of substrate combinations. Furthermore, the versatility of the aza-Henry strategy for preparing nonsymmetric cis-imidazolines is illustrated by a comparison of the roles of aryl nitromethane and aryl aldimine in the key step, which revealed unique substrate electronic effects providing direction for aza-Henry substrate-catalyst matching. This method was used to prepare highly substituted cis-4,5-diaryl imidazolines that project unique aromatic rings, and these were evaluated for MDM2-p53 inhibition in a fluorescence polarization assay. The diversification of access to cis-stilbene diamine-derived imidazolines provided by this platform should streamline their further development as chemical tools for disrupting protein-protein interactions.

Desulfurilative self-coupling reaction of 1,3-thiazolidine-2-thiones and intramolecular non-bonded S?S interaction in the crystallographic structure of the products

An attempt at an asymmetric Pummerer-type reaction of trans-4-benzyloxythiane-1-oxide (1) with 3-trifluoroacetyl-4S-isopropyl-1,3-thiazolidine-2-thione (2) resulted in failure but an attractive desulfurilative self-coupling reaction of 4S-isopropyl-1,3-thiazolidine-2-thione (6) occurred to give 4S-isopropyl-3-(4S-isopropyl-1,3-thiazolin-2-yl)-1,3-thiazolidine-2-thione (5). The same desulfurilative self-coupling reaction of compound 6 or 11 efficiently proceeded by treatment of diphenyl sulfoxide (7a) or methyl phenyl sulfoxide (7b) with 2 or 3-trifluoroacetyl-1,3-thiazolidine-2-thione (8) to afford each corresponding product 5 or 9. Eventually, we found a practically useful method for the synthesis of 5 and 9 by exploiting TiCl4 and sodium salt 12 or 13 of 1,3-thiazolidine-2-thiones. Interestingly, intramolecular non-bonded S?S interactions were recognized in the crystallographic structures of 5 and 9.
