In this work we synthetized the bioinspired benzoxanthene lignans (BXLs)3,14-22, and the phenazine derivative23as potential antimycotic agents. MICs and MFCs againstCandidastrains were determined. In a preliminary screening, compounds3,15,20,21,22were substantially inactive. Compounds14and17showed antifungal activity, being able to inhibit the growth of the majority ofCandidastrains with MIC values in the range 4.6-19.2 mu M (14) and 26.0-104.3 mu M (17); for three strains, the MICs were lower than those obtained using the antimycotic drug fluconazole. The three BXLs18,19and23showed some MIC values lower than that of fluconazole;18was also active against two non-albicans Candidastrains resistant to fluconazole. Phenazine23, although active only against one strain (MIC = 1.3 mu M), was one order of magnitude more potent than fluconazole. All the BXLs were fungicidal.

I found the field of Pharmacology & Pharmacy very interesting. Saw the article Hydroxyazole scaffold-based Plasmodium falciparum dihydroorotate dehydrogenase inhibitors: Synthesis, biological evaluation and X-ray structural studies published in 2019. Product Details of 98-17-9, Reprint Addresses Lolli, ML (corresponding author), Univ Turin, Dept Sci & Drug Technol, Via Pietro Giuria 9, I-10125 Turin, Italy.. The CAS is 98-17-9. Through research, I have a further understanding and discovery of 3-(Trifluoromethyl)phenol

Plasmodium falciparum dihydroorotate dehydrogenase (PJDHODH) has been clinically validated as a target for antimalarial drug discovery, as a triazolopyrimidine class inhibitor (DSM265) is currently undergoing clinical development. Here, we have identified new hydroxyazole scaffold-based PJDHODH inhibitors belonging to two different chemical series. The first series was designed by a scaffold hopping strategy that exploits the use of hydroxylated azoles. Within this series, the hydroxythiadiazole 3 was identified as the best selective PJDHODH inhibitor (IC50 12.0 mu M). The second series was designed by modulating four different positions of the hydroxypyrazole scaffold. In particular, hydroxypyrazoles 7e and 7f were shown to be active in the low mu M range (IC50 2.8 and 5.3 mu M, respectively). All three compounds, 3, 7e and 7f showed clear selectivity over human DHODH (IC50> 200 mu M), low cytotoxicity, and retained micromolar activity in P. falciparum-infected erythrocytes. The crystallographic structures of PJDHODH in complex with compounds 3 and 7e proved their binding mode, supplying essential data for future optimization of these scaffolds.

To identify novel adenosine receptor (AR) ligands based on the chalcone scaffold, herein the synthesis, characterization and in vitro and in silico evaluation of 33 chalcones (15-36 and 37-41) and structurally related compounds (42-47) are reported. These compounds were characterized by radioligand binding and GTP shift assays to determine the degree and type of binding affinity, respectively, against rat (r) A(1) and A(2A) ARs. The chalcone derivatives 24, 29, 37 and 38 possessed selective A(1) affinity below 10 mu M, and thus, are the most active compounds of the present series; compound 38 was the most potent selective A(1) AR antagonist (K-i (r) = 1.6 mu M). The structure-affinity relationships (SAR) revealed that the NH2-group at position C3 of ring A of the chalcone scaffold played a key role in affinity, and also, the Br-atom at position C3 ‘ on benzylidene ring B. Upon in vitro and in silico evaluation, the novel C3 amino-substituted chalcone derivative 38-that contains an alpha,ss-unsaturated carbonyl system and easily allows structural modification-may possibly be a synthon in future drug discovery.

The preparation of a new series of dihydridoboranes supported by N,N-chelating ligands, [R(2)NCH(2)CH(2)NAe](-) (R = alkyl, Ar = aryl), is reported. These new boranes react selectively with carbonyls, imines, and a series of electron-deficient fluoroarenes. The reactivity is complementary to recognized reagents such as pinacolborane, catecholborane, NHC-BH3, and borane (BH3) itself. Selectivities are rationalized by invoking both open- and closed-chain forms of the reagents as part of equilibrium mixtures.

Aim: Tumor cells adapt to hypoxic microenvironments by releasing the key transcription factor HIF-1 alpha, which promotes angiogenesis, glycolytic phenotype, metastasis and erythropoiesis, allowing proliferation amid low oxygen levels. Therefore, therapeutic targeting of HIF-1 alpha represents a viable strategy for cancer therapy. Methods & Results: The authors synthesized a series of novel tetrahydroquinazoline derivatives in six steps and demonstrated that their development had a unique ability to suppress HIF-1 alpha expression through proteasomal degradation. Conclusion: Among these compounds, CDMP-TQZ (8bf) exhibited the highest antiproliferative potency in human cancer cells, in part through downregulation of HIF-1 alpha.

The FDA (U.S. Food and Drug Administration) has approved only a negligible number of poly(lactide-co-glycolide) (PLGA)-based microsphere formulations, indicating the difficulty in developing a PLGA microsphere. A thorough understanding of microsphere formulations is essential to meet the challenge of developing innovative or generic microspheres. In this study, the key factors, especially the key process factors of the marketed PLGA microspheres, were revealed for the first time via a reverse engineering study on Vivitrol(R) and verified by the development of a generic naltrexone-loaded microsphere (GNM). Qualitative and quantitative similarity with Vivitrol(R), in terms of inactive ingredients, was accomplished by the determination of PLGA. Physicochemical characterization of Vivitrol(R) helped to identify the critical process parameters in each manufacturing step. After being prepared according to the process parameters revealed by reverse engineering, the GNM demonstrated similarity to Vivitrol(R) in terms of quality attributes and in vitro release (f(2) = 65.3). The research on the development of bioequivalent microspheres based on the similar technology of Vivitrol(R) will benefit the development of other generic or innovative microspheres.

An Auxiliary Activity Family 5 (AA5) copper-radical alcohol oxidase (AlcOx) with promiscuous activity towards simple alkyl and aromatic alcohols was evaluated using real-time reaction progress monitoring. Reaction kinetics using variable time normalization analysis (VTNA) were determined from reaction progress curves. By this approach, a detailed view of the entire reaction time course under various conditions was obtained and used to identify parameters that will inform further process optimization development. Optimal activity was found impacted by several factors, including reaction pH, oxygen saturation, and the source of a co-oxidant, either HRP or a chemical alternative, potassium ferricyanide. Analysis of reaction progress curves demonstrated that reaction stalling occurred as a result of oxygen depletion and from a loss of enzyme activity over time. The cooperativity between AlcOx, horseradish peroxidase (HRP), and catalase that result in enhanced reactivity was explored, with reaction pH being identified as a key factor for optimal activity. The results show that a process with HRP is more robust than with potassium ferricyanide, but that both oxidants likely activate AlcOx by a similar mechanism. The phenomenon of product inhibition was investigated for representative reactants, revealing that reaction inhibition was more significant for butyraldehyde than for benzaldehyde. Our analysis suggests that this is linked to the greater proportion in which butyraldehyde exists in the hydrated form.

The alpha-lithiobenzyloxy group, easily generated from aryl benzyl ethers by selective alpha-lithiation with t-BuLi at low temperature, behaves as a directed metalation group (DMG) providing a direct access to o-lithiophenyl alpha-lithiobenzyl ethers. This ortho-directing effect is reinforced in substrates bearing an additional methoxy group at the meta position. The generated dianions can be reacted with a selection of electrophiles including carboxylic esters and dihalosilanes or germanes, which afford interesting benzofuran, sila(germa)dihydrobenzofuran, and silachroman derivatives from simple aryl benzyl ethers.

Simple alpha-(bromomethyl)styrenes can be processed to a variety of 1,1-difluorinated electrophilic building blocks via I(I)/I(III) catalysis. This inexpensive main group catalysis strategy employs p-TolI as an effective organocatalyst when combined with Selectfluor (R) and simple amine center dot HF complexes. Modulating Bronsted acidity enables simultaneous geminal and vicinal difluorination to occur, thereby providing a platform to generate multiply fluorinated scaffolds for further downstream derivatization. The method facilitates access to a tetrafluorinated API candidate for the treatment of amyotrophic lateral sclerosis. Preliminary validation of an enantioselective process is disclosed to access alpha-phenyl-beta-difluoro-gamma-bromo/chloro esters.
