Bhat, Tahir Saleem published the artcileSafety and efficacy of ARNI (valsartan/sacubitril) vs ACEI (enalapril) in acute heart failure – A prospective observational study., Synthetic Route of 137862-53-4, the publication is Indian heart journal (2022), 74(3), 178-181, database is MEDLINE.

OBJECTIVE: To compare the safety and efficacy of valsartan/sacubitril (angiotensin receptor neprilysin inhibitor [ARNI]) against enalapril (angiotensin-converting enzyme inhibitor [ACEI]) in patients with acute heart failure at 6-month follow-up. METHODS: In this prospective, single centre, and observational study conducted between September 2017 and February 2020 in India, patients with acute decompensated heart failure with reduced ejection fraction (<40%) were included. Patients were divided in two groups: valsartan/sacubitril (ARNI) group and enalapril (ACEI). Patients were followed up for at least 6 months after administration of first dose and were evaluated for safety, efficacy, and tolerability of target drug. Student’s independent t-test was employed for comparing continuous variables. Chi-square test or Fisher’s exact test, whichever appropriate, was applied for comparing categorical variables. RESULTS: A total of 200 patients were included in the present study, 100 each in ARNI and ACEI group. The mean age of the population was 61.2 ± 8.4 years and 62.6 ± 8.6 years in ARNI group and ACEI group, respectively. The mean maximum tolerated dose by population in ARNI group was 203.6 mg and 8.9 mg in ACEI group. Readmission for heart failure were seen significantly higher in ACEI group than ARNI group (p value = 0.001). Parameters like ejection fraction, left ventricular end diastolic and systolic dimensions, 6 min walk test and Kansas City Cardiomyopathy Questionnaires (KCCQ) showed p values < 0.05 between the groups. CONCLUSION: The ARNI study group showed better safety and efficacy outcomes at the end of 6 months follow-up compared to ACEI group.

A review. Histone deacetylase (HDAC) inhibition is a recent, clin. validated therapeutic strategy for cancer treatment. HDAC inhibitors (HDACIs) block angiogenesis, arrest cell growth, and lead to differentiation and apoptosis in tumor cells. In this article, a survey of published quant. structure-activity relationships (QSARs) studies are presented and discussed in the hope of identifying the structural determinants for anticancer activity. Secondly a two-dimensional QSAR study was carried out on biol. results derived from various types of HDACIs and from different assays using the C-QSAR program of Biobyte. The QSAR anal. presented here is an attempt to organize the knowledge on the HDACIs with the purpose of designing new chem. entities with enhanced inhibitory potencies and to study the mechanism of action of the compounds This study revealed that lipophilicity is one of the most important determinants of activity. Addnl., steric factors such as the overall molar refractivity (CMR), molar volume (MgVol), the substituent’s molar refractivity (MR) (linear or parabola), or the sterimol parameters B₁ and L are important. Electronic parameters indicated as σ_p, are found to be present only in one case. © 2010 Wiley Periodicals, Inc. Med Res Rev 32:1-165, 2012.

Mohammady, Mohsen published the artcileDesign of ultra-fine carvedilol nanococrystals: Development of a safe and stable injectable formulation, Synthetic Route of 1453-82-3, the publication is European Journal of Pharmaceutics and Biopharmaceutics (2021), 139-151, database is CAplus and MEDLINE.

Carvedilol (CAR) is a strategic beta-blocker agent which its application has been limited by its very low water solubility The present study describes a soluble form of drug based on nano-cocrystal (NCC) anti-solvent precipitation technique. The COSMOquick software was employed to select the optimum coformer (tartaric acid, TA) and organic solvent (acetone) relying on the enthalpy changes of cocrystn. and solubilization. Central Composite Design (CCD) considering the impact of CAR, TA, poloxamer 188 (stabilizer) concentrations, and anti-solvent/solvent ratio on CAR NCCs particle size (PS) could produce ultra-fine NCCs (about 1 nm). The lyophilization of NCCs investigating slow/fast freezing rates, various types and concentrations of cryprotectants and lyoprotectants indicated that PEG and trehalose (5% w/v concentration) under slow freezing rate could re-produce the initial PSs successfully. CAR NCCs indicated about 2000 fold increase in solubility compared with pure CAR. DSC and PXRD experiments proved that the formulations containing trehalose led to more crystalline and the ones comprising PEG led to more amorphous structures. Interestingly, the slow freezed PEG protected NCCs were phys. stable for at least 18 mo. In conclusion, the NCC technol. could produce the first safe soluble form of CAR for treating hypertension urgencies easy for industrial scale-up.

Rausch, Keiko published the artcileScreening Bioactives Reveals Nanchangmycin as a Broad Spectrum Antiviral Active against Zika Virus, HPLC of Formula: 380315-80-0, the publication is Cell Reports (2017), 18(3), 804-815, database is CAplus and MEDLINE.

Zika virus is an emerging arthropod-borne flavivirus for which there are no vaccines or specific therapeutics. We screened a library of 2,000 bioactive compounds for their ability to block Zika virus infection in three distinct cell types with two different strains of Zika virus. Using a microscopy-based assay, we validated 38 drugs that inhibited Zika virus infection, including FDA-approved nucleoside analogs. Cells expressing high levels of the attachment factor AXL can be protected from infection with receptor tyrosine kinase inhibitors, while placental-derived cells that lack AXL expression are insensitive to this inhibition. Importantly, we identified nanchangmycin as a potent inhibitor of Zika virus entry across all cell types tested, including physiol. relevant primary cells. Nanchangmycin also was active against other medically relevant viruses, including West Nile, dengue, and chikungunya viruses that use a similar route of entry. This study provides a resource of small mols. to study Zika virus pathogenesis.

Karatzas, Anastasis published the artcileMacromolecular Architecture and Encapsulation of the Anticancer Drug Everolimus Control the Self-Assembly of Amphiphilic Polypeptide-Containing Hybrids, Application of H-Lys(Boc)-OH, the publication is Biomacromolecules (2019), 20(12), 4546-4562, database is CAplus and MEDLINE.

Macromol. architecture plays an important role in the self-assembly process of block copolymer amphiphiles. Herein, two series of stimuli-responsive amphiphilic 3-miktoarm star hybrid terpolypeptides and their corresponding linear analogs were synthesized exhibiting the same overall composition and mol. weight but different macromol. architecture. The macromol. architecture was found to be a key parameter in defining the morphol. of the nanostructures formed in aqueous solutions as well as to alter the self-assembly behavior of the polymers independently of their composition In addition, it was found that the assemblies prepared from the star-shaped polymers showed superior tolerance against enzymic degradation due to the increased corona block d. on the outer surface of the nanoparticles. Encapsulation of the hydrophobic anticancer drug Everolimus resulted in the formation of intriguing non-spherical and non-sym. pH-responsive nanostructures, such as “stomatocytes” and “multi-compartmentalized suprapolymersomes”, while the pH-triggered release of the drug was also investigated. Owing to the similarities of the developed “stomatocytes” with red blood cells, in combination with their pH-responsiveness and superior stability over enzymic degradation, they are expected to present advanced drug delivery properties and have the ability to bypass several extra- and intracellular barriers to reach and effectively treat cancer cells.

We report the copper(II)-catalyzed conversion of organoboron compounds into the corresponding azide derivatives A systematic series of phenylboronic acid derivatives is evaluated to examine the importance of steric and electronic effects of the substituents on reaction yield as well as functional group compatibility. Heterocyclic substrates are also shown to participate in this mild reaction while compounds incorporating B-C(sp³) bonds are unreactive under the reaction conditions. The copper(II)-catalyzed boronic acid-azide coupling reaction is further extended to both boronate esters and potassium organotrifluoroborate salts. The method described herein complements existing procedures for the preparation of aryl azides from the resp. amino, triazene, and halide derivatives and we expect that it will greatly facilitate copper- and ruthenium-catalyzed azide-alkyne cycloaddition reactions for the preparation of diversely functionalized 1-aryl- or 1-heteroaryl-1,2,3-triazoles derivatives
