Picolinamide group assisted sp(3) C-H bond oxidation of methylene groups to the corresponding carbonyl compounds has been achieved by using simple bottle ferrocene as catalyst and Cu(OAc)(2) or tert-butyl peroxybenzoate (TBPB) as oxidant under mild conditions. This method is applicable for picolinamide bound organic as well as organometallic compounds with yields in the range of 46-82%. Control experiments and mechanistic studies indicate that a radical mechanism is responsible for these oxidative transformations in which ferrocene acts as a catalyst.

The effect of topology on the structure, self-assembly, and selective Fe3+ binding of delta-peptides has been investigated. A series of delta-peptides with an amino acid containing dihydropyrimidinone and o-, m-, and p-aminobenzoic acids have been designed to study the structure-function relationship. A new amino acid containing dihydropyrimidinone was synthesized by the Biginelli reaction of ethyl acetoacetate, urea, and o-nitrobenzaldehyde followed by reduction with iron powder and acetic acid. X-ray crystallography sheds some light on the conformations, self-assembly, and the diverse degrees of pi-pi stacking of adjacent delta-peptide molecules. Peptides with o- or m-aminobenzoic acid form eight-membered intramolecular hydrogen-bonded turn conformations and self-assemble through intermolecular hydrogen bonds between dihydropyrimidinone units to form a butterfly-like structure. However, the delta-peptide containing p-aminobenzoic acid forms a water-mediated cage-like structure. Irrespective of the presence of the same functional groups, only the delta-peptide with o-aminobenzoic acid can selectively bind Fe3+ in methanol as well as in water. The topology plays a crucial role in the selective Fe3+ ion binding by the delta-peptide.

The HDAC inhibitor 4-tert-butyl-N-(4-(hydroxycarbamoyl)phenyl)benzamide (AES-350, 51) was identified as a promising preclinical candidate for the treatment of acute myeloid leukemia (AML), an aggressive malignancy with a meagre 24% 5-year survival rate. Through screening of low-molecular-weight analogues derived from the previously discovered novel HDAC inhibitor, AES-135, compound 51 demonstrated greater HDAC isoform selectivity, higher cytotoxicity in MV4-11 cells, an improved therapeutic window, and more efficient absorption through cellular and lipid membranes. Compound 51 also demonstrated improved oral bioavailability compared to SAHA in mouse models. A broad spectrum of experiments, including FACS, ELISA, and Western blotting, were performed to support our hypothesis that 51 dose-dependently triggers apoptosis in AML cells through HDAC inhibition.

A three-component reaction between benzyne, oxazolines and chloroform was developed for the synthesis of trichloromethylated chiral oxazolidines. Benzyne not only serves as an electrophile towards oxazolines but also acts as a base for the deprotonation of chloroform. The dual functions of benzyne enable the trichloromethylation of chiral oxazolines and thus construct chiral N, Oquaternary stereocenters.

The preparation of ORM-10921, a selective (2C)-adrenoceptor antagonist with promising anti-psychotic properties, was successfully achieved using asymmetric -alkylation of ,-unsaturated imide and Bischler-Napieralski cyclization/asymmetric reduction as the key steps. When the tetracyclic iminium 11S was used in the reduction, the diastereo-selectivity was poor, from which four stereoisomers of ORM-10921 were obtained, respectively. However, the diastereoselectivity could be significantly improved (with dr up to >97:3) when the tricyclic imine substrate 19S was applied in this reduction, suggesting an additional chelation from the side-chain methoxy group in the transition state. According to this protocol, ORM-10921 was accomplished in a highly enantioselective manner. In addition, two analogs 26Aa and 26Ba were prepared using this novel method, and the absolute configurations were unambiguously assigned by single crystal X-ray crystallography.

An effective chiral GAP methodology for preparing alpha-aminomethyl enaminones through a (R)-CSA-catalyzed asymmetric aza-Baylis-Hillman reaction is reported. Excellent yields and high diastereoselectivity could be obtained under mild conditions and convenient GAP techniques. The confirmations of the absolute configuration of N-phosphonyl imine and chiral enaminone by X-ray diffraction provides an explicit explanation of the chirality mechanism for GAP chemistry.

A series of1,2,4- and 1,3,4-oxadiazole derivatives were synthesized and evaluated for their anticancer activity. Halogenated 1,2,4-oxadiazoles were obtained from benzonitrile and coupled either lipophilic amines or with aminoalcohols. Lipophilic 1,3,4-oxadiazole derivatives were obtained through the Mannich reactions between 5-(aryl)-1,3,4-oxadiazole-2-thiol and alkylated or acylated amines. The in vitro cytotoxic effects were evaluated against 4T1- mammary carcinoma and CT26 – colon cancer cells. The best results were obtained for the 1,3,4-oxadiazole coupled to alkylated piperazine with 10-14 carbon chain moiety, with IC50 values ranging from 1.6 to 3.55 mu M for the 4T1 cell line, and from 1.6 to 3.9 mu M for the CT26.WT cell line, and selectivity index up to 19. The most potent compounds were investigated with AnnexinV and PI staining as indicative of apoptosis induction. (C) 2019 Published by Elsevier Masson SAS.

The Name is 4-Nitrobenzoic acid. Through research, I have a further understanding and discovery of 62-23-7.

Cyanobacterial pyruvate dehydrogenase multienzyme complex E1 (PDHc E1) is a potential target enzyme for finding inhibitors to control harmful cyanobacterial blooms. In this study, a series of novel triazole thiamin diphosphate (ThDP) analogs were designed and synthesized by modifying the substituent group of triazole ring and optimizing triazole-benzene linker as potential cyanobacterial PDHc E1 (Cy-PDHc E1) inhibitors. Their inhibitory activities against Cy-PDHc E1 in vitro and algicide activities in vivo were further examined. Most of these compounds exhibited prominent inhibitory activities against Cy-PDHc E1 (IC50 1.48-4.48 mu M) and good algicide activities against Synechocystis PCC6803 (EC50 0.84-2.44 mu M) and Microcystis aeruginosa FACHB905 (EC50 0.74-1.77 mu M). Especially, compound 8d showed not only the highest inhibitory activity against Cy-PDHc E1 (IC50 1.48 mu M), but also the most powerful inhibitory selectivity between Cy-PDHc E1 (inhibitory rate 98.90%) and porcine PDHc E1 (inhibitory rate only 9.54%). Furthermore, the potential interaction between compound 8d and Cy-PDHc E1 was analyzed by a molecular docking method and site-directed mutagenesis and enzymatic analysis and fluorescence spectral analysis. These results indicated that compound 8d could be used as a hit compound for further optimization and might have potential to be developed as a new algicide.
