Synthesis/Isolation of darifenacin hydrobromide by-products

During the process development in the laboratory, the purity of darifenacin hydrobromide has been tested by HPLC. Three byproduct peaks along with darifenacin 1 peak have been observed whose area percentage ranged from 0.06-0.20% by HPLC. As per the stringent regulatory requirements, the by-products above threshold of ?0.1% must be identified and characterized. All thorough study has been undertaken to synthesize and characterize these identified by-products. All the synthesized/isolated compounds have been co-injected with darifenacin hydrobromide, the relative retention times (RRT) are found to exactly match with the identified by-products. Based on their analytical and spectral data (HPLC, IR, NMR and mass), these by-products have been characterized as (3S)-N, N-bis[2-(2,3-dihydro-1-benzofuran-5- yl)ethyl]-2,2-diphenyl-2-(pyrrolidin-3-yl)acetamide (dimer-1), (3S)-N-[2-(2,3-dihydrobenzofuran-5-yl)-ethyl]-2-{1-[2-(2,3-dihydrobenzofuran- 5-yl)-ethyl]-pyrrolidin-3-yl}-2,2-diphenyl-acetamide (dimer-2) and (3R)-2-{1-[2-(2,3-dihydrobenzofuran-5-yl)- ethyl]pyrrolidin-3-yl}-2,2- diphenylacetamide (R-isomer).

pH-responsive allochroic nanoparticles for the multicolor detection of breast cancer biomarkers

Estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor-2 (HER2) are the three crucial biomarkers for the clinical diagnosis of breast cancer. Sensitive and precise detection of ER, PR, and HER2 is of great significance for the diagnosis of breast cancer. Herein, through a simple solvent-induced self-assembly process, the self-carried allochroic nanoparticles were prepared by using some hydrophobic pH indicator molecules for allochroic NPs-linked immunosorbent assay (named ALISA) of ER, PR, and HER2, respectively. Meanwhile, the introduction of bovine serum albumin (BSA) and antibody (Ab) enhanced the dispersity of the self-assembled nanoparticles as signal tags. Since the ultra-high loading and high-efficiency release of pH indicators, the ALISA exhibitssatisfactory selectivity and sensitivity, which demonstrated the great potential in the early diagnosis and postoperative monitoring of breast cancers. Furthermore, the smartphone was introduced to combine with the ALISA for point-of-care testing, indicating the high feasibility in practical applications.

Orthogonal sp3 C1-H and N-H Bond Functionalization of 1,2,3,4-Tetrahydroisoquinolines via the Ugi Four-Component Reaction

A new protocol for orthogonal sp3 C1-H and N-H bond functionalization of 1,2,3,4-tetrahydroisoquinolines has been established via the Ugi four-component reaction with aldehydes, isonitriles, and carboxylic acids. It was revealed that only the N-H bond could be functionalized when the reaction was performed in acetonitrile at room temperature; however, when the reaction was carried out in toluene at 80 C, redox-neutral sp3 C1-H bond functionalization of 1,2,3,4-tetrahydroisoquinolines was achieved. Differing from the common role of carboxylic acid as a promoter in redox-neutral amine alpha-functionalization, the carboxylic acid employed herein is also a reactant. The orthogonal process is compatible with various substrates and provides an appealing access to a library of structurally diverse 1,2,3,4-tetrahydroisoquinolines.

2-Hydroxymethyl-4-[5-(4-methoxyphenyl)-3-trifluoromethyl-1H-1-pyrazolyl] -1-benzenesulfonamide (DRF-4367): An orally active COX-2 inhibitor identified through pharmacophoric modulation

Analogs of 1,5-diarylpyrazoles with a novel pharmacophore at N1 were designed, synthesized and evaluated for the in-vitro cyclooxygenase (COX-1/COX-2) inhibitory activity. The variations at/around position-4 of the C-5 phenyl ring in conjunction with a CF3 and CHF2 groups at C-3 exhibited a high degree of potency and selectivity index (SI) for COX-2 inhibition. The in-vivo evaluation of these potent compounds with a few earlier ones indicated the 4-OMe-phenyl analog 6 and the 4-NHMe-phenyl analog 9 with a CF3, and the 4-OEt-phenyl analog 19 with a CHF2 group at C-3 to possess superior potency than celecoxib. In addition to its impressive anti-inflammatory, antipyretic, analgesic and anti-arthritic properties, compound 6 (DRF-4367) was found to possess an excellent pharmacokinetic profile, gastrointestinal (GI) safety in the long-term arthritis study and COX-2 potency in human whole blood assay. Thus, compound 6 was selected as an orally active anti-inflammatory candidate for pre-clinical evaluation.

Discovery of 2-(1H-indol-5-ylamino)-6-(2,4-difluorophenylsulfonyl)-8-methylpyrido[2,3-d]pyrimidin-7(8H)-one (7ao) as a potent selective inhibitor of Polo like kinase 2 (PLK2)

Several families of protein kinases have been shown to play a critical role in the regulation of cell cycle progression, particularly progression through mitosis. These kinase families include the Aurora kinases, the Mps1 gene product and the Polo Like family of protein kinases (PLKs). The PLK family consists of five members and of these, the role of PLK1 in human cancer is well documented. PLK2 (SNK), which is highly homologous to PLK1, has been shown to play a critical role in centriole duplication and is also believed to play a regulatory role in the survival pathway by physically stabilizing the TSC1/2 complex in tumor cells under hypoxic conditions. As a part of our research program, we have developed a library of novel ATP mimetic chemotypes that are cytotoxic against a panel of cancer cell lines. We show that one of these chemotypes, the 6-arylsulfonyl pyridopyrimidinones, induces apoptosis of human tumor cell lines in nanomolar concentrations. The most potent of these compounds, 7ao, was found to be a highly specific inhibitor of PLK2 when profiled against a panel of 288 wild type, 55 mutant and 12 lipid kinases. Here, we describe the synthesis, structure activity relationship, in vitro kinase specificity and biological activity of the lead compound, 7ao.
