J. published 《Design, synthesis and biological evaluation of biphenylamide derivatives as Hsp90 C-terminal inhibitors》.European Journal of Medicinal Chemistry published the findings.Computed Properties of C5H5BrN2 The information in the text is summarized as follows:

Modulation of Hsp90 C-terminal function represents a promising therapeutic approach for the treatment of cancer and neurodegenerative diseases. Current drug discovery efforts toward Hsp90 C-terminal inhibition focus on novobiocin, an antibiotic that was transformed into an Hsp90 inhibitor. Based on structural information obtained during the development of novobiocin derivatives and mol. docking studies, scaffolds containing a biphenyl moiety in lieu of the coumarin ring present in novobiocin were identified as new Hsp90 C-terminal inhibitors. Structure-activity relationship studies produced new derivatives that inhibit the proliferation of breast cancer cell lines at nanomolar concentrations, which corresponded directly with Hsp90 inhibition. In the part of experimental materials, we found many familiar compounds, such as 6-Bromopyridin-3-amine(cas: 13534-97-9Computed Properties of C5H5BrN2)

6-Bromopyridin-3-amine(cas: 13534-97-9) belongs to anime. Halogenation, in which one or more hydrogen atoms of an amine is replaced by a halogen atom, occurs with chlorine, bromine, and iodine, as well as with some other reagents, notably hypochlorous acid (HClO). With primary amines the reaction proceeds in two stages, producing N-chloro- and N,N-dichloro-amines, RNHCl and RNCl2, respectively. With tertiary amines, an alkyl group may be displaced by a halogen.Computed Properties of C5H5BrN2

《Synthesis of Pd@graphene oxide framework nanocatalyst with enhanced activity in Heck-Mizoroki cross-coupling reaction》 was written by Shekarizadeh, Arezoo; Azadi, Roya. Computed Properties of C5H5BrN2 And the article was included in Applied Organometallic Chemistry in 2020. The article conveys some information:

A new method was developed for producing a catalyst involving a Pd nanoparticle (NP) embedded in a graphene oxide framework (Pd@GOF) with ordered macro- and mesoporous structures. First, 5,5′-diamino-2,2′-bipyridine was selected as crosslinking for covalent modification of GO nanosheets to prepare a 3-dimensional (3D) framework with interlayer spaces in which well-dispersed and ultra-small Pd NPs in situ grew and embedded the framework. The synthesized nanopores 3D Pd@GOF can act as nanoreactors to help the reaction substrates thoroughly come into contact with the surface of Pd NPs, thereby exhibiting high activity toward the Heck reaction, rarely reported concerning Pd NPs supported on 1-side functionalized graphene. The Pd@GOF catalyst can be used 10 times without any significant loss in the catalytic activity, confirming the long-term stability of this catalyst. The covalently assembled GOF was proposed as a universal platform for hosting noble metal NPs to construct the desired metal@GOF nanocatalyst with improved activity and stability that can be used in a broad range of practical applications.

The article conveys some information:

Despite the recent reductions in the global burden of malaria, this disease remains a devastating cause of death in tropical and subtropical regions. As there is no broadly effective vaccine for malaria, prevention and treatment still rely on chemotherapy. Unfortunately, emerging resistance to the gold standard artemisinin combination therapies means that new drugs with novel modes of action are urgently needed. In this context, Plasmodium histone modifying enzymes have emerged as potential drug targets, prompting us to develop and optimize compounds directed against such epigenetic targets. A panel of 51 compounds designed to target different epigenetic enzymes were screened for activity against Plasmodium falciparum parasites. Based on in vitro activity against drug susceptible and drug-resistant P. falciparum lines, selectivity index criterion and favorable pharmacokinetic properties, four compounds, one HDAC inhibitor (1) and three DNMT inhibitors (37, 43 and 45), were selected for preclin. studies in a mouse model of malaria. In vivo data showed that 37, 43 and 45 exhibited oral efficacy in the mouse model of Plasmodium berghei infection. These compounds represent promising starting points for the development of novel antimalarial drugs. In the part of experimental materials, we found many familiar compounds, such as 6-Bromopyridin-3-amine(cas: 13534-97-9Formula: C5H5BrN2)

A series of novel N-fluoropyridyl-containing tropane derivatives, e.g., I, were synthesized and their binding affinities for the dopamine transporter (DAT), serotonin transporter (SERT) and norepinephrine (NET) were determined via competitive radioligand binding assays. Among these derivatives, compound I showed the highest binding affinity to DAT (Ki = 4.1 nM), and selectivity for DAT over SERT (5-fold) and NET (16-fold). Compound I was radiolabeled with Fluorine-18 in two steps. Regional brain distribution and ex vivo autoradiog. studies of [18F]I demonstrated that the ligand was selectively localized in the striatum region, where DAT binding sites are highly expressed. [18F]I may be useful as a potential radioligand for imaging DATs with PET.

In 2013,Guan, Ai-Ying; Liu, Chang-Ling; Huang, Guang; Li, Hui-Chao; Hao, Shu-Lin; Xu, Ying; Li, Zhi-Nian published 《Design, Synthesis, and Structure-Activity Relationship of Novel Aniline Derivatives of Chlorothalonil》.Journal of Agricultural and Food Chemistry published the findings.Computed Properties of C5H5BrN2 The information in the text is summarized as follows:

Chlorothalonil with both low cost and low toxicity is a popularly used fungicide in the agrochem. field. The presence of nucleophilic groups on this compound allows further chem. modifications to obtain novel chlorothalonil derivatives Fluazinam, another com. available agent with a broad fungicidal spectrum, has a scaffold of diaryl amine structure. To mimic this backbone structure, a variety of (un)-substituted Ph amines was used as nucleophilic agents to react with chlorothalonil to obtain compounds with a di-Ph amine structure. Via an elegant design, two leads, 2,4,5-trichloro-6-(2,4-dichlorophenylamino)-isophthalonitrile and 2,4,5-trichloro-6-(2,4,6-trichlorophenylamino)-isophthalonitrile, with potential fungicidal activity were discovered after a preliminary bioassay screen. These two leads were further modified to obtain final products by replacing the chlorine groups in the Ph ring in Ph amine with other functional groups. These functional groups with various electronic properties and spatial characteristics were considered to explore the relationship between structure and fungicidal activity. The results indicate that the electron-withdrawing group NO2 on the 4 position on the right Ph ring plays a unique role on enhancing the fungicidal activity. The compounds were identified by proton NMR and elemental anal. Bioassays demonstrated that some of the title compounds exhibited excellent fungicidal activities against cucumber downy mildew at 25 mg/L. 2,4,5-Trichloro-6-(2-chloro-4-nitrophenylamino)isophthalonitrile has been shown as the optimal structure with 85% control against cucumber downy mildew at 6.25 mg/L concentration The relationship between structure and fungicidal activity is reported. The present work demonstrates that chlorothalonil derivatives can be used as possible lead compounds for developing novel fungicides.

[18F]I demonstrated specific binding in vitro to human cancer tissues. Synthesis of reference standard II(X= F) and corresponding bromo derivative II(X = X = Br), the precursor for radiolabeling were achieved from 2,4-dichloropyrrolo[2,1-f][1,2,4]triazine in three steps with 50% overall yield. The radioproduct was obtained in 8% yield by reacting 1a with [18F]TBAF in DMSO at 170 °C at high radiochem. purity and specific activity (1-2 Ci/μmol, N = 10). The proof of concept of IGF-IR imaging with [18F]I was demonstrated by in vitro autoradiog. studies using pathol. identified surgically removed grade IV glioblastoma, breast cancer and pancreatic tumor tissues.
