Haq, Nazrul;Alghaith, Adel F.;Alshehri, Sultan;Shakeel, Faiyaz research published 《 Solubility and Thermodynamic Data of Febuxostat in Various Mono Solvents at Different Temperatures》, the research content is summarized as follows. This study examines the solubility and thermodn. of febuxostat (FBX) in a variety of mono solvents, including “water, methanol (MeOH), ethanol (EtOH), isopropanol (IPA), 1-butanol (1-BuOH), 2-butanol (2-BuOH), ethylene glycol (EG), propylene glycol (PG), polyethylene glycol-400 (PEG-400), Et acetate (EA), Transcutol-HP (THP), and DMSO (DMSO)” at 298.2-318.2 K and 101.1 kPa. The solubility of FBX was determined using a shake flask method and correlated with “van’t Hoff, Buchowski-Ksiazczak λh, and Apelblat models”. The overall error values for van’t Hoff, Buchowski-Ksiazczak λh, and Apelblat models was recorded to be 1.60, 2.86, and 1.14%, resp. The maximum mole fraction solubility of FBX was 3.06 × 10^-2 in PEG-400 at 318.2 K, however the least one was 1.97 × 10^-7 in water at 298.2 K. The FBX solubility increased with temperature and the order followed in different mono solvents was PEG-400 (3.06 × 10^-2) > THP (1.70 × 10^-2) > 2-BuOH (1.38 × 10^-2) > 1-BuOH (1.37 × 10^-2) > IPA (1.10 × 10^-2) > EtOH (8.37 × 10^-3) > EA (8.31 × 10^-3) > DMSO (7.35 × 10^-3) > MeOH (3.26 × 10^-3) > PG (1.88 × 10^-3) > EG (1.31 × 10^-3) > water (1.14 × 10^-6) at 318.2 K. Compared to the other combinations of FBX and mono solvents, FBX-PEG-400 had the strongest solute-solvent interactions. The apparent thermodn. anal. revealed that FBX dissolution was “endothermic and entropy-driven” in all mono solvents investigated. Based on these findings, PEG-400 appears to be the optimal co-solvent for FBX solubility

Hassan, Ahmad;Sahni, Jasjeet Kaur;Ali, Javed research published 《 Development and evaluation of oral nanoemulsion for the bioavailability enhancement of telmisartan》, the research content is summarized as follows. The present study aimed at developing an optimal oral nanoemulsion of telmisartan and evaluating its stability, pharmacodynamic and pharmacokinetic potential. Solubility of telmisartan was determined in various oils, surfactants & cosurfactants. Formulations were selected from the o/w nanoemulsion region from the help of pseudoternary phase diagrams and were subjected to various thermodn. stability and dispersibility tests. Optimized formulations were characterized for their percentage transmittance, refractive index, viscosity, droplet size and zeta potential & TEM. Release rate of optimized formulations was determined using an in vitro dissolution test. The formulation used for lowering of induced hypertension contained Soyabean oil (10%, volume/volume), Tween 20 (22.50%, volume/volume), Transcutol HP (7.5%, volume/volume) & double distilled water (60% volume/volume). The release of drug from the nanoemulsion formulations was highly significant (p < 0.01) in comparison to the drug suspension. More than 40% of the drug was released in the initial 1 h of the dissolution study in comparison to the drug suspension. The lowering of blood pressure in the group administered with the formulation F2 was highly significant (p < 0.01) with respect to the group administered with the marketed formulation. The plasma concentration time profile of telmisartan from oral nanoemulsion represented greater improvement of drug absorption than the marketed formulation. The shelf life of the nanoemulsion was found to be 1.5 years at room temperature The present study established oral nanoemulsion formulation to be one of the possible alternatives to traditional oral formulations of telmisartan to improve its bioavailability.

Also, the successful hydroalkenylation of enamides R¹N(R2)CH=CHR3 with alkenyl boronic acids R4B(OH)₂ in air atm. affords an elegant route to synthetically useful beta-alkenylated amines in satisfactory yields.

Based on a hit cluster of compounds inhibiting interleukin-2 inducible T-cell kinase (ITK) in the submicromolar range a series of ITK inhibitor libraries were synthesized.

While organic donor-acceptor (D-A) mols. are widely employed in multiple areas, the application of more D-A mols. could be limited because of an inherent polarity sensitivity that inhibits photochem. processes. Presented here is a facile chem. modification to attenuate solvent-dependent mechanisms of excited-state quenching through addition of a β-carbonyl-based polar substituent. The results reveal a mechanism wherein the β-carbonyl substituent creates a structural buffer between the donor and the surrounding solvent. Through computational and exptl. analyses, it is demonstrated that the β-carbonyl simultaneously attenuates two distinct solvent-dependent quenching mechanisms. Using the β-carbonyl substituent, improvements in the photophys. properties of commonly used D-A fluorophores and their enhanced performance in biol. imaging are shown.

Hostetler, Matthew A.;Smith, Chloe;Nelson, Samantha;Budimir, Zachary;Modi, Ramya;Woolsey, Ian;Frerk, Autumn;Baker, Braden;Gantt, Jessica;Parkinson, Elizabeth I. research published 《 Synthetic natural product inspired cyclic peptides》, the research content is summarized as follows. Natural products are a bountiful source of bioactive mols. Unfortunately, discovery of novel bioactive natural products is challenging due to cryptic biosynthetic gene clusters, low titers, and arduous purifications. Herein, we describe SNaPP (Synthetic Natural Product Inspired Cyclic Peptides), a method for identifying NP-inspired bioactive peptides. SNaPP expedites bioactive mol. discovery by combining bioinformatics predictions of nonribosomal peptide synthetases with chem. synthesis of the predicted natural products (pNPs). SNaPP utilizes a recently discovered cyclase, the penicillin binding protein-like cyclase, as the lynchpin for the development of a library of head-to-tail cyclic peptide pNPs. Anal. of 500 biosynthetic gene clusters allowed for identification of 131 novel pNPs. Fifty-one diverse pNPs were synthesized using solid phase peptide synthesis and solution-phase cyclization. Antibacterial testing revealed 14 pNPs with antibiotic activity, including activity against multidrug-resistant Gram-neg. bacteria. Overall, SNaPP demonstrates the power of combining bioinformatics predictions with chem. synthesis to accelerate the discovery of bioactive mols.

Hu, Qing;Lin, Han;Wang, Yanfang;Wang, Xiaoqin;Yao, Jiayi;Fu, Xiaoling;Yu, Xiangbin research published 《 Design, optimization and evaluation of a microemulsion-based hydrogel with high malleability for enhanced transdermal delivery of levamisole》, the research content is summarized as follows. The objective of the present study was to prepare and evaluate a microemulsion-based hydrogel with high malleability as a transdermal delivery carrier for levamisole (LMS). A pseudo-ternary phase diagram and D-optimal mixture design were utilized to screen and optimize the microemulsion, and the formulation comprised 7.5% MaisineTM35-1, 33% Smix and 59.5% water. The microemulsion was phys. stable with an average size of 19.3 ± 0.1 nm and zeta potential of -3.84 ± 0.05 mV. Moreover, a highly malleable alginate-boronic acid (alginate-BA) gel was prepared and could come into close contact with highly curved skin. The optimized microemulsion was loaded into alginate-BA gel and subjected to ex vivo and in vivo investigation. The microemulsion-based gel had desirable characterization, good stability and negligible skin irritation. The results of ex vivo permeation study showed that LMS achieved a significantly higher cumulative amount from the LMS-loaded microemulsion-based gel than that from the LMS-gel. The pharmacokinetic study showed a twofold increase in relative bioavailability compared to the com. liniment. These results provide insight into the capability of the developed malleable microemulsion-based gel to enhance the transdermal permeation and bioavailability of LMS.
