A simple and efficient method for the synthesis of 3-indolyl-3-hydroxy oxindoles and unsymmetrical 3,3-di(indolyl)indolin-2-ones using microwave irradiation without catalyst and solvent is described. A series of 3-indolyl-3-hydroxy oxindoles and unsymmetrical 3,3-di(indolyl)indolin-2ones have been synthesized in very short reaction times of 5 and 10 minutes and in yields ranging from 31% to 98%...

Accepted September 28, 2012 In the present study, a series of benzothiazol derivatives 3a-l containing pyrazolo[3,4-d]pyrimidine moiety at the second position were synthesized and characterized by analytical and spectral data. The compounds were tested for their in vitro antimicrobial activity. Compounds 1-(1,3-benzothiazol-2yl)-3-methyl-4-phenyl-1H-pyrazolo[3,4-d]pyrimidine (3a), 1(1,3-benzoth...

OBJECTIVE To compare the predictions of dominant Gleason pattern ≥ 4 or non-organ confined disease with Prostate Imaging Reporting and Data System (PI-RADS v2) with or without proton magnetic resonance spectroscopic imaging (1H-MRSI). MATERIALS AND METHODS Thirty-nine men underwent 3-tesla endorectal multiparametric MRI including 1H-MRSI and prostatectomy. Two radiologists assigned PI-RADS v2...

The first examples of Pt complexes of the well known anti-epilepsy drug and histone deacetylase inhibitor, valproic acid (VPA), are reported. Reaction of the Pt(II) am(m)ine precursors trans-[PtCl(2)(NH(3))(py)] and trans-[PtCl(2)(py)(2)] with silver nitrate and subsequently sodium valproate gave trans-[Pt(VPA(-1H))(2)(NH(3))(py)] and trans-[Pt(VPA(-1H))(2)(py)(2)], respectively. The valproato ...

The title compound, 5-(1H-indol-3-yl)-1-methyl-3-phenyl-1,6-benzodiazocin-2(1H)-one, was synthesized for the first time by a one-step, two-component reaction between 1-methylbenzimidazole and benzoylindolyl-3-acetylene. product characterized 1H-NMR, 13C-NMR, IR spectroscopy HRMS.

Methyl 1-aryl-3-cinnamoyl-4,5-dioxo-4,5-dihydro-1H-pyrrole-2-carboxylates interact with 3-(arylamino)-1H-inden-1-ones to give the corresponding 1,1'-diaryl-3'-cinnamoyl-4'-hydroxy-1H-spiro[indeno[1,2-b]pyrrole-3,2'-pyrrole]-2,4,5'(1'H)-triones in good yields.

Five new polyol monoterpenes (1-5) and seven new sesquiterpene lactones (6-12), along with five previously identified compounds, were isolated from the aerial parts of Artemisia suksdorfii. The structures of the new compounds were established by high-field NMR techniques (1H, 13C, 1H-1H DEPT, COSY, HMQC, and HMBC) and in case of 6 confirmed by X-ray analysis.

Graft versus host disease (GvHD) is one of the main complications after hematological stem cell transplantation (HSCT). CAMPATH-1H is used in the pre-transplant conditioning regimen to effectively reduce GvHD by targeting CD52 antigens on T cells resulting in their depletion. Information regarding CD52 expression and the effects of CAMPATH-1H on immune cells is scant and limited to peripheral b...

in view of potential biological activities of small molecule polyamides, we synthesized some novel n-(2-aminoethyl)-1-benzyl-2- (alkylthio)-1h-imidazole-5-carboxamide (7a,b), and n-(2-(1-benzyl-2-(alkylthio) -1h-imidazole- 5-carboxamido) ethyl)-1-benzyl-2- (alkylthio)-1h-imidazole-5-carboxamides (8a,b) as antitumor agents. the antitumor activity of compounds 7a,b and 8a,b was studied at concent...

A method in which 1H-1H scalar and dipolar couplings are obtained from the cross-peak nulling condition in a series of constant-time (CT) COSY spectra, as a function of the duration of the CT period, is described. The method is best suited for measurement of 1H-1H couplings in the range 5-20 Hz. It is shown, however, that results can be sensitive to cross-correlated relaxation effects. Also, ar...
