Carboxylic acid bioisosteres of gamma-linked dipeptide analogues of the folate-based thymidylate synthase (TS) inhibitor, 2-desamino-2-methyl-N10-propargyl-5,8-dideazafolic acid (ICI 198583)

Tetrazole carboxylic acid bioisosteres of gamma-linked dipeptide derivatives of 2-desamino-2-methyl-N10-propargyl-5,8-dideazafolic acid (ICI 198583), a folate-based inhibitor of thymidylate synthase (TS), were synthesised by multistep routes starting from the appropriate pteroic acid analogue and Z-D-Ala or D-Glu. They exhibited excellent TS inhibitory activities which, however, were not accompanied by a parallel improvement in the L1210 cell growth inhibition.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Formula: C10H7ClN2, you can also check out more blogs about20375-65-9

Antiplatelet Agents Based on Cyclooxygenase Inhibition without Ulcerogenesis. Evaluation and Synthesis of 4,5-Bis(4-methoxyphenyl)-2-substituted-thiazoles

The syntheses, biological evaluations, and structure-activity relationships of a series of 4,5-bis(4-methoxyphenyl)-2-substituted-thiazoles as potent antiplatelet agents with vasodilatory activity are described. 2-Guanidino-4,5-bis(4-methoxyphenyl)thiazole (3), designed from two parent compounds (itazigrel and timegadine), showed inhibitory activity of malondialdehyde (MDA, IC50 = 31 muM) production which is formed from the cyclooxygenase (CO)-catalyzed oxygenation of arachidonic acid in the synthesis of prostanoids in platelets, with vasodilatory activity (ED50 = 2.0 muM). Further structure-activity relationship studies on 3 culminated in the preparation of 4,5-bis(4-methoxyphenyl)-2-<(1-methylpiperazin-4-yl)carbonyl>thiazole (10a, FR122047) which exhibited potent inhibitory activity on MDA synthesis in vitro (IC50 = 0.088 muM) and platelet aggregation in guinea pigs ex vivo (100percent inhibition even 6 h after 1.0 mg/kg administration) with vasodilatory activity in vitro (ED50 = 6.2 muM). Moreover, 10a demonstrated no ulcerogenesis effect in rats even at 100 mg/kg dosage (safety margin in rats is more than 70 while that of aspirin is only 1.2) in spite of its potent CO inhibition (IC50 = 0.43 muM), while the use of aspirin, a CO inhibitor and the most popular thromboembolic drug, is restricted by the side effect. Pharmacokinetic studies on 10a have revealed that 10a is detectable in platelet-rich plasma but not in platelet-poor plasma 1 day after oral administration, which indicates that 10a tends to be localized in platelets. This property could be responsible for its low toxicity and reduction of side effects in clinical studies.

Novel pyridazine based scorpionate ligands in cobalt and nickel boratrane compounds

Heating of 6-methylpyridazine-3-thione (HPnMe) and 6-tert-butylpyridazine-3-thione (HPntBu) with potassium borohydride in diphenylmethane in a 3:1 ratio gave two new scorpionate ligands K[HB(Pn Me)3] and K[HB(PntBu)3]. Single crystal X-ray diffraction analysis of the methyl derivative K[HB(Pn Me)3] revealed a dimeric species with one potassium atom coordinated by six sulfur atoms of two scorpionate ligands and a second potassium atom coordinated by three nitrogen atoms of one of the two ligands as well as by three water molecules. The reaction of K[HB(PntBu) 3] with nickel(II) chloride or cobalt(II) chloride in CH 2Cl2 led to the new boratrane compounds [M{B(Pn tBu)3}Cl] (M = Ni 1, Co 3) where a formal reduction of the metal ions to Ni(I) and Co(I), respectively, and activation of the B-H bond occurred. Similar reactivity was observed by employing K[HB(PnR) 3] (R = Me, tBu) and nickel(II) chloride in water. Reaction with cobalt(II) chloride in water also gave boratrane compounds [Co{B(Pn R)3}(PnR)] (R = tBu 4, Ph 5), but instead of a chloride a bidentate pyridazinethionate ligand from a defragmentated scorpionate is found in the molecules. The molecular structures of all nickel and cobalt compounds were determined by single crystal X-ray diffraction analyses confirming the formation of boratranes in compounds 1-5. Magnetic measurements confirm the reduced oxidation states and the paramagnetic character of the Ni(I) and Co(I) complexes. Supportive DFT studies were carried out for a better understanding of the electronic nature of the metal-boron bond of the boratrane complexes.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 13327-27-0, help many people in the next few years.Application In Synthesis of 6-Methylpyridazin-3(2H)-one

Effect of Linker Stereochemistry on the Activity of Indolinobenzodiazepine Containing Antibody-Drug Conjugates (ADCs)

Antibody-drug conjugates (ADCs) that incorporate potent indolinobenzodiazepine DNA alkylators as the payload component are currently undergoing clinical evaluation. In one ADC design, the payload molecules are linked to the antibody through a peptidase-labile l-Ala-l-Ala linker. In order to determine the role of amino acid stereochemistry on antitumor activity and tolerability, we incorporated l- and d-alanyl groups in the dipeptide, synthesized all four diastereomers, and prepared and tested the corresponding ADCs. Results of our preclinical evaluation showed that the l-Ala-l-Ala configuration provided the ADC with the highest therapeutic index (antitumor activity vs toxicity).

Structure-metabolism-relationships in the microsomal clearance of piperazin-1-ylpyridazines

In this study, we provide insight into the metabolic profile of a series of piperazin-1-ylpyridazines suffering from rapid in vitro intrinsic clearance in a metabolic stability assay using liver microsomes (e.g. compound 1 MLM/HLM t1/2 = 2/3 min). Aided by empirical metabolite identification and computational predictive models, we designed the structural modifications required to improve in vitro intrinsic clearance by more than 50-fold (e.g. compound 29 MLM/HLM t1/2 = 113/105 min).
