- Two-photon absorbing compounds and methods of making same
-
A two-photon absorbing (TPA) compound is provided, along with a method of making same. The TPA compound has a general structural formula: where A is an acceptor moiety that is connected to m number of diarylaminofluorene arms (m=1-3); in each diarylaminofluorene arms, R is selected from linear or branched alkyl chains having a general formula CnH2n+1, where n is in a range from 2 to 25; where R1, R2, and R3 are independently selected from H or C1-C4 alkyls; where R4 is selected from C1-C5 alkyls; and wherein R5 through R10 are independently selected from H, alkoxyls, alkyls, or aryls. A may be benzothiazol-2-yl, benzo[1,2-d:4,5-d′]bisthiazole-2,6-diyl, thiazolo[5,4-d]thiazole-2,5-diyl-, 1,3,5-triazine-2,4,6-triyl, 1,3,5-triazine-2,4,6-triyl, benzo[1,2-d:3,4-d′:5,6-d″]tristhiazole-2,5,8-triyl-, or dithieno[3,2-b:2′,3′-d]thiophene-2,6-diyl-.

- Effect of ortho-substituents on the stereochemistry of 2-(o-substituted phenyl)-1H-imidazoline-palladium complexes
-
Palladium complexes composed of [Pd(Ln)2Cl2] (n = 1, 2, 3, 4, 6), [L5a]2[PdCl4] and [Pd(L5b)2], where L1 = 4,5-dihydro-2-phenyl-1H-imidazole (=2-phenyl-1H-imidazoline), L2 = 2-(o-fluorophenyl)-1H-imidazoline, L3 = 2-(o-methylphenyl)-1H-imidazoline, L4 = 2-(o-tert-butylphenyl)-1H-imidazoline, L5a = 2-(o-hydroxyphenyl)-1H- imidazolinium, L5b = 2-(1H-imidazolin-2-yl)phenolate, and L6 = 2-(o-methylphenyl)-1H-imidazole, were synthesized. Molecular structures of the isolated palladium complexes were characterized by single crystal X-ray diffraction analysis. The effect of ortho-substituents on the phenyl ring on trans-chlorine geometry was noted for complexes [Pd(L1)2Cl 2] 1a and 1b, [Pd(L2)2Cl2] 2 and [Pd(L6) 2Cl2] 6, whereas cis-chlorine geometry was observed for [Pd(L3)2Cl2] 3 and [Pd(L4)2Cl2] 4. PdCl2 reacts with 2-(o-hydroxyphenyl)-1H-imidazoline in DMF to give [L5a]+ and [L5b]- so that [L5a]2[PdCl 4] 5a and [Pd(L5b)2] 5b were obtained. In complex 5b, as an N,O-bidentate ligand, two ligands L5b coordinated with the central Pd(II) ion in the trans-form. The coordination of PdCl2 with 2-(o-hydroxyphenyl)-1H-imidazolines in solution was investigated by NMR spectroscopy. Palladium complexes composed of [Pd(Ln)2Cl2] (n = 1, 2, 3, 4, 6), [L5a]2[PdCl4] and [Pd(L5b)2], where L1 = 4,5-dihydro-2-phenyl-1H-imidazole (= 2-phenyl-1H-imidazoline), L2 = 2-(o-fluorophenyl)-1H-imidazoline, L3 = 2-(o-methylphenyl)-1H-imidazoline, L4 = 2-(o-tert-butylphenyl)-1H-imidazoline, L5a = 2-(o-hydroxyphenyl)-1H-imidazolinium, L5b = 2-(1H-imidazolin-2-yl) phenolate, and L6 = 2-(o-methylphenyl)-1H-imidazole, were synthesized and characterized by single crystal X-ray diffractometry.

- Identification of (R)-1-(5-tert-butyl-2,3-dihydro-1H-inden-1-yl)-3-(1H- indazol-4-yl)urea (ABT-102) as a potent TRPV1 antagonist for pain management
-
Vanilloid receptor TRPV1 is a cation channel that can be activated by a wide range of noxious stimuli, including capsaicin, acid, and heat. Blockade of TRPV1 activation by selective antagonists is under investigation by several pharmaceutical companies in an effort to identify novel agents for pain management. Here we report that replacement of substituted benzyl groups by an indan rigid moiety in a previously described N-indazole-N′-benzyl urea series led to a number of TRPV1 antagonists with significantly increased in vitro potency and enhanced drug-like properties. Extensive evaluation of pharmacological, pharmacokinetic, and toxicological properties of synthesized analogs resulted in identification of (R)-7 (ABT-102). Both the analgesic activity and drug-like properties of (R)-7 support its advancement into clinical pain trials.
