Discovery of blood-brain barrier permeable and orally bioavailable caffeine-based amide derivatives as acetylcholinesterase inhibitors. Bioorg Chem 2023; 139:106719. [PMID: 37473478 DOI: 10.1016/j.bioorg.2023.106719] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Revised: 06/10/2023] [Accepted: 07/06/2023] [Indexed: 07/22/2023]
Abstract
Caffeine is one of the privileged natural products that shows numerous effects on the central nervous system. Herein, thirty-one caffeine-based amide derivatives were synthesized and evaluated in vitro for their anticholinesterase activity. The introduction of the amide group to the caffeine core augmented its anticholinesterase activity from an IC50 value of 128 to 1.32 µM (derivative, 6i). The SAR study revealed that N7 substitution on caffeine core is favorable over N1, and the presence of amide 'carbonyl' as a part of the linker contributes to the biological activity. The caffeine core of 6i exhibits interactions with the peripheral anionic site, whereas the N-benzyl ring fits nicely inside the catalytic anionic site. Analog 6i inhibits AChE in a mixed-type mode (Ki 4.58 µM) and crosses the BBB in an in-vitro PAMPA assay. Compound 6i has a descent metabolic stability in MLM (>70% remaining after 30 min) and favorable oral pharmacokinetics in Swiss albino mice.

Pyrazolopyrimidinone Based Selective Inhibitors of PDE5 for the Treatment of Erectile Dysfunction. Chem Biodivers 2023; 20:e202200707.

Abstract
Continuing research with our earlier finding of sildenafil based analogs in the search of new inhibitors of PDE5 for erectile dysfunction suggested that there is a scope of modifications at N-methylpiperazine ring with hydrophobic region followed by hydrogen bond donor or acceptor region. However, the leads identified earlier had some limitations like poor pharmacokinetic (PK) profile, low aqueous solubility and poor bioavailability. In this direction, a new series of sildenafil based analogs were designed, synthesized and screened for their PDE5 inhibitory activity. In this series compound 18 was found to have excellent in vitro activity with selectivity towards PDE5 isozyme, also the in vivo activity and pharmacokinetic profile was excellent. The cyp inhibition and CaCO2 permeability was also excellent for compound 18.

A sensitive HPLC-FLD method for the quantification of alpelisib, a novel phosphatidylinositol 3-kinase inhibitor, in rat plasma: Drug metabolism and pharmacokinetic evaluation in vitro and in vivo. J Chromatogr B Analyt Technol Biomed Life Sci 2021; 1163:122508. [PMID: 33387858 DOI: 10.1016/j.jchromb.2020.122508] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2020] [Revised: 12/03/2020] [Accepted: 12/14/2020] [Indexed: 01/25/2023]
Abstract
Alpelisib, a novel phosphatidylinositol 3-kinase inhibitor, is an oral anticancer agent approved for the treatment of advanced or metastatic breast cancer. In this study, a sensitive bioanalytical method using high-performance liquid chromatography combined with a fluorescence detector (HPLC-FLD) was developed for the determination of alpelisib in rat plasma. This newly developed method was validated in terms of linearity (1-1,000 ng/mL), precision, accuracy, recovery, matrix effect, and stability according to the US Food and Drug Administration guideline and these parameters were within the acceptable limits. Alpelisib tended to be stable in plasma, urine, simulated intestinal fluid, and buffer with pH > 4.0 for 24 h, but in the pH 1.2 buffer and simulated gastric fluid for up to 4 h only. A study involving intravenous administration of alpelisib in rats showed that the dose-normalized area under the plasma concentration versus time curve (AUC) of alpelisib changed significantly as the dose increased from 1 to 10 mg/kg. Similarly, an oral rat study indicated that the dose-normalized AUC and the fraction of dose that remained in the gastrointestinal (GI) tract changed significantly as the dose increased from 0.5 to 10 mg/kg. These nonlinear (dose-dependent) pharmacokinetics of intravenous and oral alpelisib could be attributed to the saturation of ubiquitous metabolism among most tissues and/or GI absorption processes. To the best of our knowledge, this is the first study to investigate the in vivo nonlinear pharmacokinetics of alpelisib and its possible mechanisms, together with a new HPLC-FLD method to determine alpelisib in biological matrices.

Alkyl and Aryl Derivatives Based on p-Coumaric Acid Modification and Inhibitory Action against Leishmania braziliensis and Plasmodium falciparum. Molecules 2020; 25:molecules25143178. [PMID: 32664596 PMCID: PMC7397144 DOI: 10.3390/molecules25143178] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2020] [Revised: 06/12/2020] [Accepted: 06/17/2020] [Indexed: 02/07/2023] Open
Abstract
In low-income populations, neglected diseases are the principal cause of mortality. Of these, leishmaniasis and malaria, being parasitic, protozoan infections, affect millions of people worldwide and are creating a public health problem. The present work evaluates the leishmanicidal and antiplasmodial action of a series of twelve p-coumaric acid derivatives. Of the tested derivatives, eight presented antiparasitic activities 1–3, 8–12. The hexyl p-coumarate derivative (9) (4.14 ± 0.55 μg/mL; selectivity index (SI) = 2.72) showed the highest leishmanicidal potency against the Leishmania braziliensis amastigote form. The results of the molecular docking study suggest that this compound inhibits aldehyde dehydrogenase (ALDH), mitogen-activated kinase protein (MPK4), and DNA topoisomerase 2 (TOP2), all of which are key enzymes in the development of Leishmania braziliensis. The data indicate that these enzymes interact via Van der Waals bonds, hydrophobic interactions, and hydrogen bonds with phenolic and aliphatic parts of this same compound. Of the other compounds analyzed, methyl p-coumarate (64.59 ± 2.89 μg/mL; IS = 0.1) demonstrated bioactivity against Plasmodium falciparum. The study reveals that esters presenting a p-coumarate substructure are promising for use in synthesis of derivatives with good antiparasitic profiles.

Abstract
The erythrocyte membrane is composed of a phospholipid bilayer, which is known to undergo physicochemical changes during storage at low temperatures. This study was conducted to identify marker phospholipids that indicate alteration during deep-frozen storage and to determine the amount of marker phospholipids. Our research suggested a method to detect phospholipids by profiling analysis of thermally injured red blood cells (RBCs) without protecting agents. Human blood was stored at -80°C for 72 days. The RBC membrane phospholipids were extracted through a modified Bligh and Dyer method. Six selected phospholipids were analyzed and quantified using liquid chromatography-tandem mass spectrometry, and an in vitro model system was developed. The intracellular level of N-nervonoyl-D-erythro-sphingosylphosphorylcholine significantly increased in the thermally injured RBCs, and multiple biomarker candidates were evaluated by profiling analysis and mass spectrometry technology for targeted metabolomics.
