Effect of co-ligands on chemical and biological properties of (99m)Tc(III) complexes [(99m)Tc(L)(CDO)(CDOH)2BMe] (L=Cl, F, SCN and N3; CDOH2=cyclohexanedione dioxime).

Yumin Zheng et al.

Nuclear medicine and biology, 41(10), 813-824 (2014-08-30)

(99m)Tc-Teboroxime ([(99m)TcCl(CDO)(CDOH)2BMe]) is a member of the BATO (boronic acid adducts of technetium dioximes) class of (99m)Tc(III) complexes. This study sought to explore the impact of co-ligands on solution stability, heart uptake and myocardial retention of [(99m)Tc(L)(CDO)(CDOH)2BMe] ((99m)Tc-Teboroxime: L=Cl; (99m)Tc-Teboroxime(F):

Straightforward and efficient synthesis of 3-benzyloxy-4-bromopicolinate ester and 3-benzyloxy-5-bromopicolinate ester, common building blocks for pharmaceuticals and agrochemicals

Ultrafast 2,7-Naphthyridine-Based fluorescent probe for detection of thiophenol with a remarkable Stokes shift and its application In vitro and in vivo.

Rui Ren et al.

Talanta, 205, 120067-120067 (2019-08-28)

2,7-Naphthyridine derivatives were developed as fluorophores for the first time to design two fluorescence probes, AND-DNP and ND-DNP, which can be applied for detecting thiophenol in aqueous media. Comparing with ND-DNP, AND-DNP showed more favorable properties such as lower background

Establishment of Biosynthetic Pathways To Generate Castasterone as the Biologically Active Brassinosteroid in Brachypodium distachyon.

Jeehee Roh et al.

Journal of agricultural and food chemistry, 68(13), 3912-3923 (2020-03-10)

Gas chromatography-mass spectrometry (GC-MS) analysis revealed that castasterone and its biosynthetic precursors are found in Brachypodium distachyon. In vitro conversion experiments with crude enzyme solutions prepared from B. distachyon demonstrated the presence of the following biosynthetic sequences: campesterol → campesta-4-en-3-one

Suzuki-Miyaura cross-couplings of secondary allylic boronic esters.

Ben W Glasspoole et al.

Chemical communications (Cambridge, England), 48(9), 1230-1232 (2011-12-20)

Palladium-catalyzed cross-coupling reactions of secondary allylic boronic esters with iodoarenes were demonstrated under the conditions previously described for the coupling of benzylic substrates. The regioselectivity of the process was largely dictated by the pattern of olefin substitution.

Asymmetric bromolactonization using amino-thiocarbamate catalyst.

Ling Zhou et al.

Journal of the American Chemical Society, 132(44), 15474-15476 (2010-10-16)

A novel amino-thiocarbamate-catalyzed bromolactonization of unsaturated carboxylic acids has been developed. The scope of the reaction is evidenced by 22 examples of γ-lactones with up to 99% yield and 93% ee. The protocol was applied in the enantioselective synthesis of

Enol tosylates as viable partners in Pd-catalyzed cross-coupling reactions.

Dietrich Steinhuebel et al.

The Journal of organic chemistry, 70(24), 10124-10127 (2005-11-19)

[reaction: see text] Herein we demonstrate functionalized enol tosylates to be robust substrates that undergo Suzuki-Miyaura, Sonogashira, and Stille cross-coupling reactions to provide stereodefined trisubstituted unsaturated esters.

A comparative study of ethylene polymerization by bis(aminotropone) Ti catalysts

A chrysin analog exhibited strong inhibitory activities against both PGE2 and NO production.

Haiyan Che et al.

European journal of medicinal chemistry, 46(9), 4657-4660 (2011-07-02)

A number of 8-substituted chrysin analogs have been prepared and evaluated for their inhibitory activities of cyclooxygenase-2 catalyzed prostaglandin E(2) and iNOS-mediated NO production. Analogs were prepared via Suzuki-Miyaura C-C cross coupling reaction of 8-iodo-5,7-dimethoxyflavone and alkyl/areneboronic acids as a

Selective heating of Pd-modified ordered mesoporous carbon CMK-3 by microwave irradiation

Enantioselective bromoaminocyclization using amino-thiocarbamate catalysts.

Ling Zhou et al.

Journal of the American Chemical Society, 133(24), 9164-9167 (2011-05-05)

A facile and efficient enantioselective bromoaminocyclization of unsaturated sulfonamides has been developed using an amino-thiocarbamate catalyst. A range of enantioenriched pyrrolidines were prepared with up to 99% yield and 99% ee. The corresponding lactams could be obtained through oxidation of

Divergent C-H functionalizations directed by sulfonamide pharmacophores: late-stage diversification as a tool for drug discovery.

Hui-Xiong Dai et al.

Journal of the American Chemical Society, 133(18), 7222-7228 (2011-04-15)

Modern drug discovery is contingent on identifying lead compounds and rapidly synthesizing analogues. The use of a common pharmacophore to direct multiple and divergent C-H functionalizations of lead compounds is a particularly attractive approach. Herein, we demonstrate the viability of
