supporting information, p. 5629 - 5633 (2014/07/22)
Hydrogen sulfide (H2S) has been regarded as the third gaseous transmitter. Based on the mechanism of chemoselective azido reduction and self-immolation, five fluorescence resonance energy transfer (FRET) probes for the detection of H2S were designed and synthesized. The effect of functional substitution of the self-immolative moiety on azido reduction and quinone-methide rearrangement were investigated. Their fluorescence responses and chemoselectivity for H2S detection were evaluated in solutions and in cells. This strategy may provide a general route for designing H 2S probes with many commercially available FRET pairs. the Partner Organisations 2014.

PHARMACEUTICALLY ACCEPTABLE SALTS OF 2-{4-[(3S)-PIPERIDIN-3- YL]PHENYL} -2H-INDAZOLE-7-CARBOXAMIDE
-
Page/Page column 35, (2009/09/04)
The present invention relates to pharmaceutically acceptable salts of an amide substituted indazole which are inhibitors of the enzyme poly(ADP-ribose)polymerase (PARP), previously known as poly(ADP-ribose)synthase and poly(ADP-ribosyl)transferase. The compounds of the present invention are useful as mono-therapies in tumors with specific defects in DNA-repair pathways and as enhancers of certain DNA -damaging agents such as anticancer agents and radiotherapy. Further, the compounds of the present invention are useful for reducing cell necrosis (in stroke and myocardial infarction), down regulating inflammation and tissue injury, treating retroviral infections and protecting against the toxicity of chemotherapy.

scheme or table, p. 4416 - 4420 (2010/04/05)
Synthesis and biological evaluation of various colchicine analogues through the mixed-lymphocyte reaction (MLR), lymphoproliferation, and inhibitory effects on the inflammatory genes are described. In addition, a new series of immunosuppressive agents developed on the structural basis of colchicine, as well as their structure-activity relationships is reported. The most potent analogue 20a exhibited an excellent immunosuppressive activity on in vivo skin-allograft model, which is comparable to that of cyclosporin A.
Discovery of 2-{4-[(3S)-piperidin-3-yl]phenyl}-2H-indazole-7-carboxamide (MK-4827): A novel oral poly(ADP-ribose)polymerase (PARP) inhibitor efficacious in BRCA-1 and -2 mutant tumors

We disclose the development of a novel series of 2-phenyl-2H-indazole-7- carboxamides as poly(ADP-ribose) polymerase (PARP) 1 and 2 inhibitors. This series was optimized to improve enzyme and cellular activity, and the resulting PARP inhibitors display antiproliferation activities against BRCA-1 and BRCA-2 deficient cancer cells, with high selectivity over BRCA proficient cells. Extrahepatic oxidation by CYP450 1A1 and 1A2 was identified as a metabolic concern, and strategies to improve pharmacokinetic properties are reported. These efforts culminated in the identification of 2-{4-[(3S)-piperidin-3-yl] phenyl}-2H-indazole-7-carboxamide 56 (MK-4827), which displays good pharmacokinetic properties and is currently in phase I clinical trials. This compound displays excellent PARP 1 and 2 inhibition with IC50 = 3.8 and 2.1 nM, respectively, and in a whole cell assay, it inhibited PARP activity with EC50 = 4 nM and inhibited proliferation of cancer cells with mutant BRCA-1 and BRCA-2 with CC50 in the 10-100 nM range. Compound 56 was well tolerated in vivo and demonstrated efficacy as a single agent in a xenograft model of BRCA-1 deficient cancer.
