Structure-Based Drug Discovery of N-((R)-3-(7-Methyl-1H-indazol-5-yl)-1-oxo-1-(((S)-1-oxo-3-(piperidin-4-yl)-1-(4-(pyridin-4-yl)piperazin-1-yl)propan-2-yl)amino)propan-2-yl)-2 ‘-oxo-1 ‘,2 ‘-dihydrospiro[piperidine-4,4 ‘-pyrido[2,3-d][1,3]oxazine]-1-carboxamide (HTL22562): A Calcitonin Gene-Related Peptide Receptor Antagonist for Acute Treatment of Migraine

Structure-based drug design enabled the discovery of 8, HTL22562, a calcitonin gene-related peptide (CGRP) receptor antagonist. The structure of 8 complexed with the CGRP receptor was determined at a 1.6 angstrom resolution. Compound 8 is a highly potent, selective, metabolically stable, and soluble compound suitable for a range of administration routes that have the potential to provide rapid systemic exposures with resultant high levels of receptor coverage (e.g., subcutaneous). The low lipophilicity coupled with a low anticipated clinically efficacious plasma exposure for migraine also suggests a reduced potential for hepatotoxicity. These properties have led to 8 being selected as a clinical candidate for acute treatment of migraine.

A facile one-pot synthesis of 1H-pyrano[2,3-d]pyrimidin-4(5H)-ones and evaluation of their Ct-DNA interaction, antibacterial and anti-inflammatory activity

In this paper, we reported the synthesis of coumarin-pyrimidine derivatives by a four-component reaction involving 4-hydroxycoumarin, aldehyde, thiobarbituric acid and piperidine in ethanol. All the synthesized compounds were well-characterized by IR, NMR and mass spectroscopic techniques. Further, to evaluate the biological potency of the synthesized compounds, initially, DNA cleavage studies were performed. Encouraged by the results obtained from the cleavage studies, the synthesized compounds were screened for in-vitro antibacterial and anti-inflammatory activity. From the biological activity results, it revealed that most of the synthesized compounds were found to exhibit potent antimicrobial and anti-inflammatory activity with least IC50 than compared with standard.

Potent, non-covalent reversible BTK inhibitors with 8-amino-imidazo[1,5-a] pyrazine core featuring 3-position bicyclic ring substitutes

Bruton’s tyrosine kinase (BTK) is a Tec family kinase with a well-defined role in the B cell receptor (BCR) pathway. It has become an attractive kinase target for selective B cell inhibition, and for the treatment of B cell related diseases. Many BTK inhibitors have been discovered for the treatment of cancer and rheumatoid arthritis, including a series of BTK inhibitors based on 8-amino-imidazo[1,5-a]pyrazine we recently reported. The X-ray crystal structures of BTK with inhibitors were also published, which provided great help for the SAR design. Here we report our SAR work introducing ring constraints for the 3-position piperidine amides on the BTK inhibitors based on 8-amino-imidazo[1,5-a]pyrazine. This modification improved the potency in BTK inhibitions, as well as the PK profile and the off-target selectivity. The dose-dependent efficacy of two BTK inhibitors was observed in the rat collagen induced arthritis (CIA) model.

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 41661-47-6 help many people in the next few years. HPLC of Formula: C5H9NO.

Development of a new photosafety test method based on singlet oxygen generation detected using electron spin resonance

Photosafety evaluations of chemicals used in consumer products, such as pharmaceuticals and cosmetics, are very important. Currently, two non-animal tests for photosafety evaluations, the in vitro 3T3 neutral red uptake phototoxicity test (NRU PT) and the reactive oxygen species (ROS) assay, are used to detect photoreactive chemicals. However, these two tests are difficult to apply to hydrophobic chemicals. In the present study, we attempted to develop a new photosafety test method, named the electron spin resonance-based photosafety test (ESR-PT), that would be applicable even to hydrophobic chemicals based on the detection of singlet oxygen generation after irradiation using ESR spectroscopy with 4-hydroxy-2,2,6,6-tetramethyl-piperidine as a spin trap reagent. To achieve a quantitative evaluation, the singlet oxygen formation (SOF) value, which can be calculated as the increment in relative intensity after irradiation of the test mixture normalized by the increment in relative intensity after irradiation of the vehicle control solution, was calculated. The performance of the ESR-PT was evaluated by testing all the proficiency chemicals of the ROS assay plus additional chemicals, including hydrophobic chemicals and chemicals that tested false negative in the 3T3-NRU PT and ROS assay. SOF values were successfully calculated for all the chemicals tested including the hydrophobic chemicals, and the accuracy of the ESR-PT using a tentative cutoff value of 2.8 against the photosafety information was 100%. Therefore, the SOF value could be an effective parameter for photosafety evaluations, suggesting that the newly developed ESR-PT is a promising non-animal test applicable even to hydrophobic chemicals.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 388077-74-5, in my other articles.

Synthesis and pharmacological evaluation of novel cis and trans 3-substituted anilidopiperidines

Background 4-Anilidopiperidine class of synthetic opioid analgesics, with it’s representative fentanyl, are by far the most potent and clinically significant for the treatment of the severe chronic and surgical pain. However, side effects of mu-opioids are often quite serious. In order to improve the pharmacological profile of this class of opioid analgesics, a novel fentanyl analogs were designed, synthesized and evaluated in vivo for their antinociceptive activity. Methods The title compounds were prepared using known synthetic transformations, includingN-bromoacetamide mediated Hofmann rearrangement, highly selective carbamate cleavage with trimethylsilyl iodide and dehydration of carboxamide group to nitrile in the presence of SOCl2. The antinociceptive activity of the synthesized compounds was determined by tail-immersion and formalin test. Results The scalable synthetic route towards novel fentanyl analogs bearing nitrogen groups in position C(3)of piperidine ring is designed. In addition, Hofmann rearrangement was substantially improved for the more efficient synthesis of previously published 3-substituted fentanyl analogs. The series of ten fentanyl analogs was tested in vivo for their antinociceptive activity. The most potent compound of the series was found to becis-4, based on the determined ED(50)values in tail-immersion test. Conclusion Of ten compounds tested for their antinociceptive activity, compoundcis-4is characterized by high potency, rapid beginning and short duration of action and due to this might be incorporated in different pharmaceutical forms.

Switching Electrophile Intermediates to Nucleophiles: Michael and Oxa-Diels-Alder Reactions to Afford Polyoxy-Functionalized Piperidine Derivatives with Tetrasubstituted Carbon

Michael, Michael-annulation, and oxa-Diels-Alder reactions of carbohydrate derivatives that afford polyoxy-functionalized piperidine derivatives bearing tetrasubstituted carbon at the 3-position of the piperidine ring are reported. Iminium ions generated from carbohydrate derivatives with amines were converted to enamines in situ, which acted as nucleophiles. As a result, substituents were introduced at the 3-position or both 2- and 3-positions of the piperidines bearing polyoxy groups. This strategy will be useful in drug discovery efforts.

Synthesis of novel spiropiperidine derivatives and their antimicrobial and antioxidant activities

A series of novel spiro-piperidinyl pyrazolones are synthesized by the reaction of N-Boc protected ethyl nipecotate with heteroaryl and alkyl aldehydes in presence of lithium diisopropyl amide (LDA) to yield corresponding beta-hydroxy ester, followed by MnO2 oxidation to give beta-keto ester. Further reaction of beta-keto ester with hydrazine hydrate results in the formation of spiro-piperidinyl pyrazolone scaffold 5a-d which upon N-benzylation followed by deprotection yields compounds 7a-s. The pyrazolone-NH group has been alkylated in compound 5a with ethyl chloroacetate followed by hydrolysis and amide coupling to afford compounds 9a-d. The furan ring in compound 5a is oxidized to carboxylic acid with KMnO4 and coupled with amines to prepare amide derivatives 11a-c. All the synthesized compounds are evaluated for their in vitro antibacterial and antioxidant activity. Compounds 7a-d and 7g-s are found to possess high antibacterial activity and compounds 7a,7b, 9a, 9b, 11a and 11c are found to be potent antioxidants.

Sample Flow Rate Scan in Electrospray Ionization Mass Spectrometry Reveals Alterations in Protein Charge State Distribution

Sample flow rate is one of the parameters that influence the sensitivity of electrospray ionization (ESI) mass spectrometry. By varying the sample flow rate, initial droplets of different sizes can be generated. Protein molecules in small droplets may form gas-phase ions earlier than the ones in large droplets. Here, we have systematically studied the influence of sample flow rate on the ESI charge state distributions (CSDs) of model proteins. A dedicated programmable sample flow rate scanner was used to infuse protein samples at different flow rates into a mass spectrometer. The synergistic influence of sample flow rate and various electrolytes (ammonium acetate, ammonium bicarbonate, ammonium formate, and piperidine) was studied. Significant alterations to the CSDs with increasing flow rate were observed. For example, in the presence of ammonium acetate, at low flow rates, lower charge states of proteins showed high intensities, while at high flow rates, ions related to higher charge states of proteins dominated the spectra. On the other hand, in the presence of piperidine, a significant reduction in the ion currents of all charge states was observed during the flow rate scan. Our observations suggest that at low flow rates the protein molecules follow a charged residue model of ionization mechanism, and at high flow rates-due to structural changes in protein molecules in large ESI droplets-the charged residue and chain ejection models can possibly coexist. We propose the use of sample flow rate scan as a way to reveal the influence of flow rate on the CSDs of the studied proteins.
