With the infection rate of Bordetella pertussis at a 60-year high, there is an urgent need for new anti-pertussis vaccines. The lipopolysaccharide (LPS) of B. pertussis is an attractive antigen for vaccine development. With the presence of multiple rare sugars and unusual glycosyl linkages, the B. pertussis LPS is a highly challenging synthetic target. In this work, aided by molecular dynamics simulation and modeling, a pertussis-LPS-like pentasaccharide was chemically synthesized for the first time. The pentasaccharide was conjugated with a powerful carrier, bacteriophage Q beta, as a vaccine candidate. Immunization of mice with the conjugate induced robust anti-glycan IgG responses with IgG titers reaching several million enzyme-linked immunosorbent assay (ELISA) units. The antibodies generated were long lasting and boostable and could recognize multiple clinical strains of B. pertussis, highlighting the potential of Q beta-glycan as a new anti-pertussis vaccine.

Direct utilization of the abundant hydrogen in water for the transfer hydrogenation reaction (THR) is a very attractive and challenging research area. Herein, we report the first integrated photo-transfer hydrogenation reaction (PTHR) platform for the synthesis of benzhydrol derivatives (26 examples, 33-89% yields) with water as a green reducing agent. This transformation is time and labor-efficient, catalyst-free, and economical and utilizes readily available hydrocarbon(s) (o-methyl phenyl ketones) as starting materials.

Two series of racemic goniothalamin analogues displaying nitrogen-containing groups were designed and synthesized. A total of 19 novel analogues were evaluated against a panel of four different cancer cell lines, along with the normal prostate cell line PNT2 to determine their selectivity. Among them, goniothalamin chloroacrylamide 13 e displayed the lowest IC50 values for both MCF-7 (0.5 mu m) and PC3 (0.3 mu m) cells, about 26-fold more potent than goniothalamin (1). Besides its higher potency, compound 13 e also displayed much higher selectivity than goniothalamin. In contrast, goniothalamin isobutyramide 13 c was the most potent analogue against Caco-2 cells (IC50=0.8 mu m), about 10-fold more potent and 17-fold more selective than 1. These results reveal the potential of compounds 13 c and 13 e for further in vivo studies, representing the first goniothalamin analogues with IC50 values in the low micromolar range and high selectivity against MCF-7, Caco-2, and PC3 cancer cell lines.

Transcriptional enhancer associated domain family members (TEADs) are the most important downstream effectors that play the pivotal role in the development, regeneration and tissue homeostasis. Recent biochemical studies have demonstrated that TEAD5 could undergo autopalmitoylation that is indispensable for its function making the lipid-binding pocket an attractive target for chemical intervention. Herein, through structure-based virtual screen and rational medicinal chemistry optimization, we identified DC-TEADin02 as the most potent, selective, covalent TEAD autopalmitoylation inhibitor with the IC50 value of 197 +/- 19 nM while it showed minimal effect on TEAD-YAP interaction. Further biochemical counter-screens demonstrate the specific thiol reactivity and selectivity of DC-TEADin02 over the kinase family, lipid-binding proteins and epigenetic targets. Notably, DC-TEADin02 inhibited TEADs transcription activity leading to downregulation of YAP-related downstream gene expression. Taken together, our findings proved the validity of modulating transcriptional output in the Hippo signaling pathway through irreversible chemical interventions of TEAD5 autopalmitoylation activity, which may serve as a qualified chemical tool for TEADs palmitoylation-related studies in the future.

A library of 1,2,4-oxadiazole functionalized quinoline derivatives (13a-j) were synthesized and their structures were confirmed by H-1 NMR, (CNMR)-C-13 and Mass Spectral analysis. Further, these compounds were evaluated for their anticancer activity against four human cancer cell lines, namely MCF-7 (breast), A549 (lung), DU-145 (prostate) and MDA MB-231 (breast) using Etoposide as the positive control. Most of these derivatives exhibited more potent activity towards the four cancer cell lines compared to Etoposide. Amongst all the compounds tested, compounds 13b, 13c, 13h, 13i and 13j exhibited promising activity. Further of these compounds 13b, 13i and 13j exhibited excellent activity, when compared with Etoposide.

Prostate Cancer (PCa) is the most frequently diagnosed cancer in men in their late ’50s. PCa growth is mainly due to the activation of the androgen receptor by androgens. The treatment for PCa may involve surgery, hormonal therapy, and oral chemotherapeutic drugs. A structural based molecular docking approach revealed the findings of (E)-N’-((1-chloro-3,4-dihydronaphthalen-2-yl)methylene)benzohydrazide derivatives, where the possible binding modes of the compounds with protein (PDB ID: 3V49) are shown. The compounds (6a-k) were synthesized and characterized by using conventional methods. The compounds, 6g, 6j, and 6k were reconfirmed through single crystal X-ray diffraction (XRD). Further, the compounds (6a-k) and standard drug were evaluated against human prostate cancer cell lines, LNCaP and PC-3 and the non-cancerous cell line, 3T3. Among these compounds, 6g and 6j showed higher cytotoxicity, and 6g exhibited dose-dependent activity and reduced cell viability. The mechanism of action was observed through the induced apoptosis and was further confirmed by western blot and ELISA. Molecular dynamics simulation studies were carried out to calculate the interaction and the stability of the protein-ligand complex in motion. ADME properties were predicted for all the tested compounds. These findings may give vital information for further development.

Catalysts that control stereochemistry are prized tools in chemical synthesis. When an effective catalyst is found, it is often explored for other types of reactions, frequently under the auspices of different mechanisms. As successes mount, a unique catalyst scaffold may become viewed as privileged. However, the mechanistic hallmarks of privileged catalysts are not easily enumerated or readily generalized to genuinely different classes of reactions or substrates. We explored the concept of scaffold uniqueness with two catalyst types for an unusual atropisomerselective cyclodehydration: (a) C-2-symmetric chiral phosphoric acids and (b) phosphothreonine-embedded, peptidic phosphoric acids. Pragmatically, both catalyst scaffolds proved fertile for enantioselective/atroposelective cyclodehydrations. Mechanistic studies revealed that the determinants of often equivalent and high atroposelectivity are different for the two catalyst classes. A data-descriptive classification of these asymmetric catalysts reveals an increasingly broad set of catalyst chemotypes, operating with different mechanistic features, that creates new opportunities for broad and complementary application of catalyst scaffolds in diverse substrate space.

A.] King Fahd Univ Petr & Minerals, Ctr Refining & Petrochem, POB 5040, Dhahran 31261, Saudi Arabia published Effective and selective direct aminoformylation of nitroarenes utilizing palladium nanoparticles assisted by fibrous-structured silica nanospheres in 2020, Cited 67.

Palladium nanoparticles (similar to 1-3 nm, 0.4 wt% Pd) were uniformly distributed over the surface of fibrous silica nanospheres (KCC-1) modified via aminopropyltriethoxysilane using a fast and cost-effective palladium (II) chloride reduction process. The Pd nanoparticles (Pd NPs) distribution over the ensuing catalyst Pd/KCC-1-NH2 showed much more uniform distribution, and smaller size compared with the tedious hydrothermal reduction method. The morphological, chemical, and size analyses of Pd/KCC-1-NH2 by BET, UV-Vis spectra, XRD, HR-TEM, EDS and XPS analysis revealed that the succeeding material consist of a distinct fibrous silica nanospheres support adorn with Pd NPs. The resultant nanocatalyst was tested for the one-step reductive aminoformylation of aromatic nitro compounds using formic acid. A wide range of substituted nitroarenes including electron withdrawing, releasing, sterically hindered and multifunctional groups have been converted to corresponding aryl formamide in quantitative yields (yields up to 98%) at moderate temperature (70 degrees C). Optimization study has proved that the 6 equivalent of formic acid is required and toluene was found to be the better solvent. The established practice is beneficial due to the use of formic acid as H-2 source and formylating agent, easiness in handling of the catalyst and simple workup procedure with efficient catalyst reusability.
