Electric Literature of C5H2Cl2N4. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: 2,6-Dichloropurine, is researched, Molecular C5H2Cl2N4, CAS is 5451-40-1, about Scaffold hopping of the SYK inhibitor entospletinib leads to broader targeting of the BCR signalosome. Author is Jorda, Radek; Krajcovicova, Sona; Kralova, Petra; Soural, Miroslav; Krystof, Vladimir.

Spleen tyrosine kinase (SYK) and Bruton’s tyrosine kinase (BTK) are attractive targets in human haematol. malignancies with excessively activated B-cell receptor (BCR) signalling pathways. Entospletinib is a SYK inhibitor that has been evaluated as a clin. candidate. Design and synthesis of five isosteres in which the imidazo[1,2-a]pyrazine scaffold of entospletinib was altered to pyrazolo[3,4-d]pyrimidine, pyrrolo[3,2-d]pyrimidine, imidazo[4,5-b]pyridine, imidazo[4,5-c]pyridine and purine is reported. The last two isosteres were the most potent SYK inhibitors, with IC50 values in the mid-nanomolar range. Importantly, three compounds also inhibited BTK more effectively than did entospletinib. Further experiments then showed that BCR signalling was suppressed in Ramos cells by the potent compounds Preliminary kinase inhibition screening also revealed LCK and SRC as addnl. targets. These results further support the hypothesis that multikinase targeting compounds could produce more robust responses in the treatment of B lymphoid neoplasms.

Let’s take a look at the latest research on this compound (cas:5451-40-1).

Seliciclib is a cyclin-dependent kinase (CDK) inhibitor that has been assayed in phase II clin. trials as an anticancer agent. This paper describes the synthesis of novel derivatives of seliciclib with improved potency, metabolic stability, aqueous solubility, and anti-proliferative activity. The new derivatives showed a novel CDKs selectivity profile. Replacement of Et alc. at position 2 of purine with dimethylaminopropyl and fluorination of benzyl at position 6 of purine of seliciclib resulted in the formation of a derivative that potently and selectively inhibited CDK9 (26 nM vs. CDK9 and > 60-fold selectivity vs. CDK2/5/7). In comparison to seliciclib, this derivative shows lower metabolic clearance (25% lower in Clint), higher aqueous solubility and is more cytotoxic in androgen-independent prostate cancer cells.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 5451-40-1, is researched, Molecular C5H2Cl2N4, about Promising 2,6,9-trisubstituted purine derivatives for anticancer compounds: synthesis, 3D-QSAR, and preliminary biological assays, the main research direction is trisubstituted purine regioselective preparation SAR QSAR antitumor apoptosis human; 3D-QSAR; apoptosis; cancer; cell cycle; cytotoxicity; purine derivatives.Reference of 2,6-Dichloropurine.

Two series of 2,6,9-trisubstituted purine derivatives I [R1 = Et, n-Bu, n-hexyl, etc.; R2 = cyclopentyl, cyclohexyl, cycloheptanyl, etc.] and II [R3 = 4-CF3OC6H4, 4-phenyl-piperidin-1-yl, 4-phenyl-piperazin-1-yl, 4-(4-chlorophenyl)piperazin-1-yl, etc.; R4 = Cl, 5-(nitropyridin-2-yl)piperazin-1-yl, 4-(pyrazin-2-yl)piperazin-1-yl, etc.; R5 = n-pentyl, n-hexyl, cyclopentyl] were synthesized and evaluated for their prospective role as antitumor compounds Compounds I and II were tested for their in vitro cell toxicity on seven cancer cells lines and one non-neoplastic cell line. Structural requirements for antitumor activity on two different cancer cell lines were analyzed with SAR and 3D-QSAR. The 3D-QSAR models showed that steric properties could better explain the cytotoxicity of compounds than electronic properties (70% and 30% of contribution, resp.). From this anal., conclusion was that arylpiperazinyl system connected at position 6 of the purine ring was beneficial for cytotoxic activity, while the use of bulky systems at position C-2 of the purine was not favorable. Compound II [R3 = 4-(4-nitrophenyl)piperazin-1-yl; R4 = Cl; R5 = cyclopentyl] was found to be an effective potential agent when compared with a currently marketed drug, cisplatin, in four out of the seven cancer cell lines tested. Compound II [R3 = 4-(4-nitrophenyl)piperazin-1-yl; R4 = Cl; R5 = cyclopentyl] showed the highest potency, unprecedented selectivity and complied with all the Lipinski rules. Finally, it was demonstrated that compound II [R3 = 4-(4-nitrophenyl)piperazin-1-yl; R4 = Cl; R5 = cyclopentyl] induced apoptosis and caused cell cycle arrest at the S-phase on HL-60 cells.

Synthesis of a key fragment of islatravir (MK-8591), a novel nucleoside reverse transcriptase translocation inhibitor (NRTTI) currently under investigation for treatment and pre-exposure prophylaxis (PrEP) against HIV infection was discussed. The fragment, the unnatural nucleobase 2-fluoroadenine, was incorporated into MK-8591 via a biocatalytic aldol-glycosylation cascade, which imposed stringent requirements for its synthesis and isolation. Presented herein was the development work leading to a practical, scalable route from guanine, featuring a dual fluorination approach to a novel 9-THP-2,6-difluoropurine intermediate that enables a mild, highly selective, direct amination. This one-pot fluorination/amination sequence utilized a direct isolation to deliver high purity 9-THP-2-fluoroadenine, which features ideal properties with respect to reactivity, solubility, and crystallinity. An acid-catalyzed liberation of 2-fluoroadenine in aqueous buffer delivers the appropriate purity profile to facilitate the enzymic cascade to access MK-8591.
