Nizamuddin, Nd; Abdul ahad, Hindustan; Devanna, Nayakanti published the artcile< Molecular docking studies of N-methyl- 2, 3 -disubstituted quinazolin-4-ones scaffold>, SDS of cas: 57493-24-0, the main research area is methyl disubstituted quinazolinone scaffold mol docking.

In recent days, synthesis of anticancer mols. having both low adverse effects and specific protein targeting are seldom. Synthesis of anticancer mols. having both low adverse effects and specific protein targeting is challenging. The main objective of our study was to develop mols. that can target activated protein kinase P38 alpha and activin receptor (ALK2) kinase for treating carcinoma. P38 alpha is involved in cell differentiation, apoptosis, and autophagy. Activin receptor (ALK2) kinase is responsible for mutations of cancerous cells. The synthesis of N-Me – 2, 3 -Disubstituted Quinazolin-4-Ones was carried out by refluxing of 1-methyl-2-(pyridinyl)-1,2-dihydro-4H-3,1-benzoxazin-4-one with 4-substituted phenyl-1,3-thiazol-2-amines. The mol. docking of 1-methyl-3-(4-substituted phenyl-1,3-thiazol-2-yl)-2-(pyridin-3-yl)-2,3-dihydroquinazolin-4(1H)-one (5Da1-5Dk11) and 1-methyl-3-(4-substituted phenyl-1,3-thiazol-2-yl)-2-(pyridin-4-yl)-2,3-dihydroquinazolin-4(1H)-one (5Ea1-5Ek11) derivatives were carried out using Schrodinger Glide (version 2020_1) software. Twenty-two quinazoline-4-one derivatives were docked into selective P38 alpha and ACVR1 (ALK2) kinase with PDB code 3GC7, 6GI6. Based on the docking score, comparison between quinazolin-4-one derivatives, co-crystallized Ligands interaction was evaluated using 5-Fluorouracil as standard Best activity was found in compounds 5Df6, 5Dd4, 5Ed4 and 5Ef6 with ACVR1 (ALK2) kinase with score of -8.223, -7.936, -8.123, -7.907 and 5Df6, 5Dh8, 5Eb2 and 5Ee5 with P38alpha with score of -7.19, -7.027, -6.698, -6.789 Kcal/mol against enzymes responsible for treatment for cancer compare with reference drug score -5.765 and -6.195. This study will help in the design and development of a drug that gives room for the synthesis of a new selective ACVR1 (ALK2) kinase and P38alpha enzyme inhibitor with predetermined affinity and activity of the compound

Hagen, Susan E.; Domagala, John; Gajda, Christopher; Lovdahl, Michael; Tait, Bradley D.; Wise, Eric; Holler, Tod; Hupe, Donald; Nouhan, Carolyn; Urumov, Andrej; Zeikus, Greg; Zeikus, Eric; Lunney, Elizabeth A.; Pavlovsky, Alexander; Gracheck, Stephen J.; Saunders, James; VanderRoest, Steve; Brodfuehrer, Joanne published the artcile< 4-Hydroxy-5,6-dihydropyrones as inhibitors of HIV protease: the effect of heterocyclic substituents at C-6 on antiviral potency and pharmacokinetic parameters>, Category: thiazole, the main research area is hydroxydihydropyrone HIV protease inhibitor antiviral agent.

Due largely to the emergence of multi-drug-resistant HIV strains, the development of new HIV protease inhibitors remains a high priority for the pharmaceutical industry. Toward this end, the authors previously identified a 4-hydroxy-5,6-dihydropyrone lead compound (CI-1029) which possesses excellent activity against the protease enzyme, good antiviral efficacy in cellular assays, and promising bioavailability in several animal species. The search for a suitable back-up candidate centered on the replacement of the aniline moiety at C-6 with an appropriately substituted heterocycle. In general, this series of heterocyclic inhibitors displayed good activity (in both enzymic and cellular tests) and low cellular toxicity; furthermore, several analogs exhibited improved pharmacokinetic parameters in animal models. The compound with the best combination of high potency, low toxicity, and favorable bioavailability was (S)-3-(2-tert-butyl-4-hydroxymethyl-5-methyl-phenylsulfanyl)-4-hydroxy-6-isopropyl-6-(2-thiophen-3-yl-ethyl)-5,6-dihydro-pyran-2-one (I). This thiophene derivative also exhibited excellent antiviral efficacy against mutant HIV protease and resistant HIV strains. For these reasons, I was chosen for further preclin. evaluation.

Kirubakaran, Sivapriya; Gorla, Suresh Kumar; Sharling, Lisa; Zhang, Minjia; Liu, Xiaoping; Ray, Soumya S.; MacPherson, Iain S.; Striepen, Boris; Hedstrom, Lizbeth; Cuny, Gregory D. published the artcile< Structure-activity relationship study of selective benzimidazole-based inhibitors of Cryptosporidium parvum IMPDH>, Recommanded Product: Thiazole-5-carboxyaldehyde, the main research area is benzimidazole inhibitor Cryptosporidium parvum IMPDH preparation SAR antiparasitic activity.

Cryptosporidium parasites are important waterborne pathogens of both humans and animals. The Cryptosporidium parvum and Cryptosporidium hominis genomes indicate that the only route to guanine nucleotides is via IMP dehydrogenase (IMPDH). Thus the inhibition of the parasite IMPDH presents a potential strategy for treating Cryptosporidium infections. A selective benzimidazole-based inhibitor of C. parvum IMPDH (CpIMPDH) was previously identified in a high throughput screen. Herein is reported a structure-activity relationship study of benzimidazole-based compounds that resulted in potent and selective inhibitors of CpIMPDH. Several compounds display potent antiparasitic activity in vitro.

Puhakka, Emmi; Santala, Ville published the artcile< Method for acrylic acid monomer detection with recombinant biosensor cells for enhanced plastic degradation monitoring from water environments>, Application In Synthesis of 2591-17-5, the main research area is acrylic acid monomer detection plastic degradation; Acrylic acid; Biosensor cells; Monomer detection; Plastic degradation; Poly(acrylic acid); Water environments.

Plastic debris degrades in the water environments due to various factors such as mech. stress. Small-sized degradation products, including plastic monomers, are currently monitored using equipment which might be unsuitable for screening. Here, we developed a recombinant whole-cell bacterial biosensor, which could be used for this type of monitoring. The Escherichia coli pBAV1K-ACU-lucFF cells contain a luciferase-based reporter system under the control of acrylic acid specific promoter. The biosensor cells were used to detect acrylic acid monomers from both sterile water and spiked lake water samples, indicating usability with environmental samples. Furthermore, poly(acrylic acid) was incubated in salt water, and the biosensor cells could identify acrylic acid monomers originating from it. Thus, the cells could be used to observe similar processes in the environment. The results show that the bacterial biosensors could complement the current research methods of plastic monomer monitoring in water environments with a potential for higher throughputs.

S-H activation reaction of thiols employing dibenzyl azodicarboxylate (DBAD) had been developed for the preparation of sulfenamides I [R = H; R1 = Et, Bn, cyclopropyl, cyclopentyl, cyclohexyl; RR1 = (CH2)4, (CH2)6, (CH2)2O(CH2)2, etc.; X = O, S]. The dehydrogenation of thiols and amines under these reaction conditions involved the formation of dibenzyl hydrazine-1,2-dicarboxylate, which led to the S-N bond formation reaction. The reaction proceeded efficiently with release of dibenzyl hydrazine-1,2-dicarboxylate and afforded various sulfenamides I in good to excellent yields.
