The one-step strategy for the facile syntheses of structurally diverse 1-indanones in moderate to good isolated yields was developed via a ruthenium-catalyzed tandem coupling and cyclization of simple aromatic acids with alpha,beta-unsaturated ketones. The tandem cyclization involves one-pot sequential reactions of C-H activation, conjugate addition, Dieckmann condensation, Michael addition, intramolecular Aldol reaction, or hydrolysis. Switchable access to spiroindanones and 2-substituted 1-indanones could be achieved by manganese additive and H2O. Mn(II) additive is found to play an important role in this transformation, and a trace amount of water can promote the formation of 2-substituted 1-indanones. This process features the one-pot efficient construction of multiple C-C bonds, high step-economy, commercially available starting materials, and a broad substrate scope.

The work is focused on the design of drugs that prevent and treat Alzheimer’s disease (AD) and its complications. A series of 3-(4-aminophenyl)-coumarin derivatives designed, synthesised, fully characterised and evaluated in vitro/vivo. The biological assay experiments showed that some compounds displayed a clearly selective inhibition for acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE). Among all compounds, compound 4m exhibited the highest AChE inhibition with an IC50 value of 0.091 +/- 0.011 mu M and compound 4k exhibited the highest BuChE inhibition with an IC50 value of 0.559 +/- 0.017 mu M. A zebrafish behaviour analyser (Zebrobox) was used to determine the behavioural effects of the active compound on the movement distance of the aluminium chloride-induced zebrafish. Compound 4m offered a potential drug design concept for the development of therapeutic or preventive agents for AD and its complications.

A series of new Olaparib derivatives was designed and synthesized, and their inhibitory activities against poly (ADP-ribose) polymerases-1 (PARP-1) enzyme and cancer cell line MDA-MB-436 in vitro were evaluated. The results showed that compound 5l exhibited the most potent inhibitory effects on PARP-1 enzyme (16.10 +/- 1.25 nM) and MDA-MB-436 cancer cell (11.62 +/- 2.15 mu M), which was close to that of Olaparib. As a PARP-1 inhibitor had been reported to be viable to neuroprotection, in order to search for new multitarget-directed ligands (MTDLs) for the treatment of Alzheimer’s disease (AD), the inhibitory activities of the synthesized compounds against the enzymes AChE (from electric eel) and BChE (from equine serum) were also tested. Compound 5l displayed moderate BChE inhibitory activity (9.16 +/- 0.91 mu M) which was stronger than neostigmine (12.01 +/- 0.45 mu M) and exhibited selectivity for BChE over AChE to some degree. Molecular docking studies indicated that 5l could bind simultaneously to the catalytic active of PARP-1, but it could not interact well with huBChE. For pursuit of PARP-1 and BChE dual-targeted inhibitors against AD, small and flexible non-polar groups introduced to the compound seemed to be conducive to improving its inhibitory potency on huBChE, while keeping phthalazine-1-one moiety unchanged which was mainly responsible for PARP-1 inhibitory activity. Our research gave a clue to search for new agents based on AChE and PARP-1 dual-inhibited activities to treat Alzheimer’s disease.

alpha-Aryl oxindoles are accessed from isatin via a two-step procedure involving a phospha-Brook rearrangement and a Friedel-Crafts alkylation in a one-pot procedure. The use of 1,1,1,3,3,3-hexafluoro-2-propanol as solvent significantly extended the reaction substrate scope to include relatively less electron-rich arenes including benzene. This new alkylation method is fast and straightforward and allows for the direct introduction of the oxindole moiety onto a range of aromatic compounds including phenols. Additionally, the application of arylated products was shown in decarboxylative asymmetric allylation and protonation.

Cross-coupling reactions have developed into powerful approaches for carbon-carbon bond formation. In this work, a Ni-catalyzed migratory Suzuki-Miyaura cross-coupling featuring high benzylic or allylic selectivity has been developed. With this method, unactivated alkyl electrophiles and aryl or vinyl boronic acids can be efficiently transferred to diarylalkane or allylbenzene derivatives under mild conditions. Importantly, unactivated alkyl chlorides can also be successfully used as the coupling partners. To demonstrate the applicability of this method, we showcase that this strategy can serve as a platform for the synthesis of terminal, partially deuterium-labeled molecules from readily accessible starting materials. Experimental studies suggest that migratory cross-coupling products are generated from Ni(0/II) catalytic cycle. Theoretical calculations indicate that the chain-walking occurs at a neutral nickel complex rather than a cationic one. In addition, the original-site cross-coupling products can be obtained by alternating the ligand, wherein the formation of the products has been rationalized by a radical chain process.

A metal-free and selective oxidation of benzylic alcohols which leads to the direct and sustainable production of benzaldehydes has been developed. Compared with former known oxidation reactions like Swern, Pfitzner-Moffatt, Parikh-Doering, and Corey-Kim oxidations, this oxidation approach introduces the HCA as an easily available, safer and less expensive reagent, and also because of the simple removing of chloroform. In addition, it is not necessary to add any metal, acid or base for the oxidation of benzylic alcohols. The oxidation is proceeded in DMSO and also under solvent-free conditions in excellent yields.

Name: 3-Methylbenzoic acid. I found the field of Biochemistry & Molecular Biology; Chemistry very interesting. Saw the article Design, synthesis and SAR study of 3rd-generation taxoids bearing 3-CH3, 3-CF3O and 3-CHF2O groups at the C2-benzoate position published in 2020.0, Reprint Addresses Ojima, I (corresponding author), SUNY Stony Brook, Dept Chem, Stony Brook, NY 11794 USA.. The CAS is 99-04-7. Through research, I have a further understanding and discovery of 3-Methylbenzoic acid.

It has been shown that inclusion of CF3O and CHF2O groups to drug candidates often improve their pharmacological properties, especially metabolic stability, membrane permeability and PK profile. Moreover, the unique non-spherical structure of the OCHF2 group can provide interesting and beneficial characteristics. Accordingly, new 3rd-generation taxoids, bearing 3-OCF3 or 3-OCF2H (and 3-CH3 for comparison) at the C2 benzoate moiety, were synthesized and their potencies against drug-sensitive and drug-resistant cancer cell lines examined. In this study, our previous SAR studies on 3rd-generation taxoids were expanded to disclose that CH3, CF3O and CHF2O groups are well tolerated at this position and enhance potency, especially against MDR-cancer cell lines so that these taxoids can virtually overcome MDR. These new taxoids exhibit up to 7 times higher cytotoxicity (IC50) than paclitaxel against drug-sensitive cancer cell lines (MCF7 and LCC6-WT) and 2-3 orders of magnitude higher potency than paclitaxel against drug-resistant ovarian, breast and colon cancer cell lines with MDR-phenotype (NCI/ADR, LCC6-MDR and LDL-1), as well as pancreatic cancer cell line, CFPAC-1. Since it has been shown that a bulky group at this position reduces potency, it is noteworthy that rather bulky CF3O and CHF2O groups are well tolerated. Molecular modeling analysis indicated the favorable van der Waals interactions of CF3O and CHF2O groups in the binding site. It is also worthy of note that new taxoids, bearing a CHF2O group at the C2 benzoate position (1-06 series), exhibited the highest potencies against MDR-cancer cell lines and cancer stem cell (CSC)-enriched cancer cell lines. These new 3rd-generation taxoids are promising candidates for highly potent chemotherapeutic agents, as well as payloads for tumor-targeting drug conjugates such as antibody-drug conjugates (ADCs).
