The oxidative coupling of carboxylic acids with liquid ketones and cyclic ethers has been accomplished in minutes using t-butyl hydroperoxide in the presence of tetrabutylammonium iodide under microwave irradiation in the absence of a solvent. In addition to drastically shortening the reaction times, the use of microwaves resulted, in general, in yields equal to or higher than those obtained by conventional heating.

SCM-198 (Leonurine) has attracted great attention due to its cardioprotective effects in myocardial infarction (MI). However, no systematic modifications and structure-activity relationship (SAR) studies could be traced so far. In this study, 35 analogs of SCM-198 were designed, synthesized and their cardioprotective effects were evaluated. The cell viability assay on cardiomyocyte cell line H9c2 challenged with H2O2 showed that several analogs exhibited more potent cytoprotective effects than SCM-198 at 1 mu M and 10 mu M concentrations. LDH release level in cells treated with 1 mu M 14o was comparable with cells treated with 10 mu M SCM-198. Results of Bcl-2 expression and caspase-3 activation accordingly indicated higher protective activity of 14o than SCM-198. Moreover, in a mouse model of MI, the mice pretreated with 14o had much lower infarct size compared with that of SCM-198. The mechanism study suggested that 14o improved cardiac morphology and reduced apoptosis of cardiomyocytes in the border zone of infarction, as proved by H&E and TUNEL staining.

An expeditious method for the synthesis of homo and heterochiral dipeptides containing L-alanine and D/L 2-methyl allo-hydroxyl prolines was developed using direct aminolysis of bicyclic lactones derived from D/L alanine. The impact of C-2 methylation and its spatial orientation on the pyrrolidine ring puckering and prolyl amide bond configuration was ascertained by solution NMR studies. The present studies reveal that C-2 methylation causes the prolyl amide bond to exist exclusively in the trans geometry in both homo-and heterochiral dipeptides. However, the spatial orientation of the C-2 methyl group and its i + 2 position in appropriately capped model dipeptides may nucleate into a turn like structure.

This paper emphasizes the preparation of nonlinear optical (NLO) responsive chromophores and their corresponding polymers. Initially, the carboxyl acid group-based precursors of the chromophores containing strong acceptors such as nitro-substituted thiazole and thiadiazole groups were prepared and subjected to condensation reactions with a monomer to yield a series of polymers. Prior to the synthesis of the polymers, a thermally crosslinkable monomer, 2,6-di-(octy-1-nyl)-p-phenylenediamine, was synthesized by a Sonogashira coupling reaction. All the synthesized precursors, the monomer and their corresponding polymers were characterized using FTIR, H-1 NMR, and CHN analyses and UV-Vis spectrophotometry. Simultaneously, the molecular structures of the precursors were designed and optimized using the Gaussian 16 (Revision A.03) program. The dipole moments, energy band gaps between the HOMO and LUMO, polarizabilities and first order hyperpolarizabilities of the precursors were calculated theoretically using the DFT approach; the values were in the ranges of 9.4321-15.3354 D, 1.3709-1.4146 eV, 53.40-64.80 x 10(-24) esu and 3703.35-5254.90 x 10(-32) esu, respectively. The inherent viscosities (eta inh) of the polymers were measured by an Ubbelohde viscometer and were in the range of 0.2453-0.2860 dl g(-1). The thermal behavior of the polymers was investigated using DSC and TGA. The glass transition temperatures of the polymers were in the range of 190-218 degrees C. The thicknesses and refractive indices of the thin films were determined by ellipsometry, and the values were in the range of 0.100-0.127 mu m and 1.211-1.426, respectively. The molecular orientations in the thin polymer films were induced by corona poling and were ascertained using both a UV-Vis spectrophotometer and an atomic force microscope. The second harmonic generations (SHGs) of the poled polymers were determined using an Nd-YAG laser. The SHG coefficients (d(33)) ranged between 98.30 and 106.04 pm V-1 at 532 nm. Among the synthesized polymers, the polymer containing dinitro-substituted thiazole demonstrated an excellent SHG coefficient as high as 106.04 pm V-1. Furthermore, none of the polymers showed SHG decay below 100 degrees C, and they retained 95% of their SHG values even up to 600 h. Based on its enhanced NLO efficiency and long temporal stability, the polymer containing dinitro-substituted thiazole can be a particularly promising candidate for photonic devices.

Matrix metalloproteinases (MMPs) are major modulators of the tumor microenvironment. They participate in extracellular matrix turnover, tumor growth, angiogenesis and metastasis. Accordingly, MMPs inhibition seems to be ideal solution to control cancer. Many MMPs inhibitors have been introduced ranging from hydroxamate-based peptidomimetics to the next generation non-hydroxamate inhibitors. Among MMPs, MMP-9 is attractive druggable anticancer target. Studies showed that inhibiting AKT, the central signaling node of MMP-9 upregulation, provides additional MMP-9 blockade. Furthermore, caspase-dependent AKT cleavage leads to cell death. Herein, Ugi MCR was utilized as a rapid combinatorial approach to generate various decorated bis-amide scaffolds as dual MMP-9/AKT inhibitors endowed with caspase 3/7 activation potential. The target adducts were designed to mimic the thematic structural features of non-hydroxamate MMP inhibitors. p-Nitrophenyl isonitrile 1 was utilized as structure entry to Ugi products with some structural similarities to amide-based caspase 3/7 activators. Besides, various acids, amines and aldehydes were employed as Ugi educts to enrich the SAR data. All adducts were screened for cytotoxicity against normal fibroblasts and three cancer cell lines; MCF-7, NFS-60 and HepG-2 utilizing MTT assay. 8,11 and 28 were more active and safer than doxorubicin with single-digit nM IC50 and promising selectivity. Mechanistically, they exhibited dual MMP-9/AKT inhibition at single-digit nM IC50 with excellent selectivity over MMP-1,-2 and -13, and induced >51% caspase 3/7 activation. Consequently, they induced >49% apoptosis as detected by flow cytometric analysis, and inhibited cell migration (metastasis) up to 97% in cancer cells. Docking simulations were nearly consistent with enzymatic evaluation, also declared possible binding modes and essential structure features of active compounds. In silico physicochemical properties, ligand efficiency and drug-likeness metrics were reasonable for all adducts. Interestingly, 8 and 28 can be considered as drug-like candidates.

A rhodium catalyzed copper mediated double oxidative annulation of propargylamino phenyl benzamides is developed. A quick assembly of tri, tetra and penta cyclic pyrido/isoquinolo-quinoxilines are thus achieved from readily available linear substrates. The reaction is shown to be very general by accommodating a large variety of substrates in the transformation. A mechanism through an amide directed C-H bond activation followed by an intramolecular alkyne activation/annulation followed by an oxidation is postulated.

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.
