The author of the article were Williamson, Douglas S.; Smith, Garrick P.; Mikkelsen, Gitte K.; Jensen, Thomas; Acheson-Dossang, Pamela; Badolo, Lassina; Bedford, Simon T.; Chell, Victoria; Chen, I-Jen; Dokurno, Pawel; Hentzer, Morten; Newland, Samantha; Ray, Stuart C.; Shaw, Terry; Surgenor, Allan E.; Terry, Lindsey; Wang, Yikang; Christensen, Kenneth V.. The article conveys some information:

Inhibitors of leucine-rich repeat kinase 2 (LRRK2) and mutants, such as G2019S, have potential utility in Parkinson’s disease treatment. Fragment hit-derived pyrrolo[2,3-d]pyrimidines underwent optimization using X-ray structures of LRRK2 kinase domain surrogates, based on checkpoint kinase 1 (CHK1) and a CHK1 10-point mutant. (2R)-2-Methylpyrrolidin-1-yl derivative I (LRRK2 G2019S cKi 0.7 nM, LE 0.66) was identified, with increased potency consistent with an X-ray structure of 18/CHK1 10-pt. mutant showing the 2-Me substituent proximal to Ala147 (Ala2016 in LRRK2). Further structure-guided elaboration of I gave the 2-[(1,3-dimethyl-1H-pyrazol-4-yl)amino] deriv II. Optimization of II afforded diastereomeric oxolan-3-yl derivatives III and IV, which demonstrated a favorable in vitro PK profile, although they displayed species disconnects in the in vivo PK profile, and a propensity for P-gp- and/or BCRP-mediated efflux in a mouse model. Compounds III and IV demonstrated high potency and exquisite selectivity for LRRK2 and utility as chem. probes for the study of LRRK2 inhibition.

《Design and synthesis of triple inhibitors of janus kinase (JAK), histone deacetylase (HDAC) and Heat Shock Protein 90 (HSP90)》 was written by Yao, Lianbin; Ohlson, Sten; Dymock, Brian W.. Reference of 2,4-Dichloro-7H-pyrrolo[2,3-d]pyrimidineThis research focused ontriple inhibitor JAK2 histone deacetylase HSP90 antitumor drug design; HDAC; HSP90; Janus kinase; Multiple ligand; Transient drug. The article conveys some information:

Inhibition of multiple signaling pathways in a cancer cell with a single mol. could result in better therapies that are simpler to administer. Efficacy may be achieved with reduced potency against individual targets if there is synergy through multiple pathway inhibition. To achieve this, it is necessary to be able to build multi-component ligands by joining together key pharmacophores in a way which maintains sufficient activity against the individual pathways. Designed triple inhibiting ligands are explored aiming to block three completely different target types: a kinase (JAK2), an epigenetic target (HDAC) and a chaperone (HSP90). Although these enzymes have totally different functions they are related through inter-dependent pathways in the developing cancer cell. Synthesis of several complex multi-inhibiting ligands are presented along with initial enzyme inhibition data against 3 biol. target classes of interest. A lead compound, 47 (I), was discovered which had low micromolar activity for all 3 targets. Further development of these complex trispecific designed multiple ligands could result in a ‘transient drug’, an alternative combination therapy for treating cancer mediated via a single mol. After reading the article, we found that the author used 2,4-Dichloro-7H-pyrrolo[2,3-d]pyrimidine(cas: 90213-66-4Reference of 2,4-Dichloro-7H-pyrrolo[2,3-d]pyrimidine)

《Redox-Active Reagents for Photocatalytic Generation of the OCF3 Radical and (Hetero)Aryl C-H Trifluoromethoxylation》 was written by Zheng, Weijia; Lee, Johnny W.; Morales-Rivera, Cristian A.; Liu, Peng; Ngai, Ming-Yu. Category: pyrimidinesThis research focused ontrifluoromethoxyarene trifluoromethoxyheteroarene preparation; arene heteroarene radical trifluoromethoxylation ruthenium photocatalyst; arenes; photocatalysis; radicals; trifluoromethoxylating reagents; trifluoromethoxylation. The article conveys some information:

The trifluoromethoxy (OCF3) radical is of great importance in organic chem. Yet, the catalytic and selective generation of this radical at room temperature and pressure remains a longstanding challenge. Herein, the design and development of a redox-active cationic reagent (1) that enables the formation of the OCF3 radical in a controllable, selective, and catalytic fashion under visible-light photocatalytic conditions is reported. More importantly, the reagent allows catalytic, intermol. C-H trifluoromethoxylation of a broad array of (hetero)arenes and biorelevant compounds Exptl. and computational studies suggest single electron transfer (SET) from excited photoredox catalysts to 1 resulting in exclusive liberation of the OCF3 radical. Addition of this radical to (hetero)arenes gives trifluoromethoxylated cyclohexadienyl radicals that are oxidized and deprotonated to afford the products of trifluoromethoxylation. In the experiment, the researchers used many compounds, for example, 2,4,6-Trichloropyrimidine(cas: 3764-01-0Category: pyrimidines)

2,4,6-Trichloropyrimidine(cas: 3764-01-0) is a member of organic chlorides.

Structure-Activity Relationships of 4-Oxopyrimidines Leading to the Selection of a Clinical Candidate》.Related Products of 659729-09-6 The author mentioned the following in the article:

A series of novel 4-oxopyrimidine TRPV1 antagonists was evaluated in assays measuring the blockade of capsaicin or acid-induced influx of calcium into CHO cells expressing TRPV1. The investigation of the structure-activity relationships in the heterocyclic A-region revealed the optimum pharmacophoric elements required for activity in this series and resulted in the identification of subnanomolar TRPV1 antagonists. The most potent of these antagonists were thoroughly profiled in pharmacokinetic assays. Optimization of the heterocyclic A-region led to the design and synthesis of 23 (I), a compound that potently blocked multiple modes of TRPV1 activation. Compound 23 was shown to be effective in a rodent “”on-target”” biochem. challenge model (capsaicin-induced flinch, ED50 = 0.33 mg/kg p.o.) and was antihyperalgesic in a model of inflammatory pain (CFA-induced thermal hyperalgesia, MED = 0.83 mg/kg, p.o.). Based on its in vivo efficacy and pharmacokinetic profile, compound 23 (N-{4-[6-(4-trifluoromethyl-phenyl)-pyrimidin-4-yloxy]-benzothiazol-2-yl}-acetamide; AMG 517) was selected for further evaluation in human clin. trials.

Hasegawa, Tetsuya; Seki, Toshinobu; Juni, Kazuhiko; Saneyoshi, Mineo; Kawaguchi, Takeo published their research in Journal of Pharmaceutical Sciences on December 31 ,1993. The article was titled 《Prodrugs of 2′,3′-didehydro-3′-deoxythymidine》.Recommanded Product: 122567-97-9 The article contains the following contents:

Six ester prodrugs of 2′,3′-didehydro-3′-deoxythymidine (I) were prepared, and their physicochem. properties evaluated. Marked differences were observed All of the prodrugs were chem. stable within the pH range 2-7. Hydrolysis of these esters was observed in all cases for 4 rat enzyme systems (plasma, liver, duodenum, and kidney), with I being regenerated. I or the prodrug was administered orally to rats, and the plasma concentrations of I and a corresponding prodrug were measured. The half-life of I after i.v. administration was 35.9 min. The half-life calculated from the terminal phase and the maximum concentration in plasma following oral administration of I were 35.9 min and 48.4 μM, resp. After oral prodrug administration (with water or olive oil as a solvent), though none of the prodrugs was detected in plasma except for 5′-hemisuccinyl derivative of I and 5′-hemiglutaryl derivative of I with olive oil as a solvent, retention time of plasma I concentration was extended and the elevated I concentration in plasma decreased.((2S,5R)-5-(5-Methyl-2,4-dioxo-3,4-dihydropyrimidin-1(2H)-yl)-2,5-dihydrofuran-2-yl)methyl benzoate(cas: 122567-97-9Recommanded Product: 122567-97-9) was used in this study.

C.; Miller, Joseph; Moritz, A. G.; Paul, David B.. And the article was published in Australian Journal of Chemistry in 1969. HPLC of Formula: 14001-69-5 The author mentioned the following in the article:

The sigma complexes formed from the reaction of MeO- with 5-nitropyrimidine and its monomethoxy derivatives were examined spectroscopically. Structural ambiguities resulting from the lower symmetry of the nitropyrimidines compared with the trinitrobenzenes were resolved by selective deuteration. Comparison is made with sigma complex formation from 2,4,6-trinitroanisole and the question of kinetic against thermodynamic control is considered with reference to theoretically derived potential energy-reaction coordinate profiles for protic solvents. The calculations are extended qual. to consider reactions in an aprotic solvent.2-Methoxy-5-nitropyrimidine(cas: 14001-69-5HPLC of Formula: 14001-69-5) was used in this study.

In 2015,Linton, Maria Angelica; Burke, Benjamin J.; Johnson, Ted W.; Ninkovic, Sacha; Gajiwala, Ketan S.; Richardson, Paul; Le, Phuong T. published 《Effect of water solvation on the lipophilicity of isomeric pyrimidine-carboxamides》.Bioorganic & Medicinal Chemistry published the findings.Related Products of 3764-01-0 The information in the text is summarized as follows:

Incorporation of nitrogen is a common medicinal chem. tactic to reduce log D values. Neighboring group participation influences log D, so the results are isomer dependent. The log D and log P differences observed between isomeric pyrimidines 1, 2 and 3 presumably result when the carbonyl or ether lone pairs are in close proximity to a heterocyclic nitrogen lone pair, recruiting water to bridge between the electron rich atoms. Various lipophilicity calculators did not discriminate between 1 (log D = 2.6) and 3 (log D = 1.0), but solvation energies using Poisson-Boltzmann and 3D-RISM methods rationalize the observed differences in lipophilicity among pyrimidine carboxamide isomers.
