The chalcone motif can be found in many molecules that contribute to essential biological processes, and many chalcone-containing compounds exhibit potent anti-cancer activity. Here, we synthesized two series of chalcone analogues (3a-s and 6a-s) based on substituting the chalcone B-ring or A-ring with a 4-oxoquinazolin-2-yl group, and then evaluated them for cytotoxic activity in human colorectal HCT-116 and breast cancer MCF-7 cell lines. Compounds 3a-s (in which a 4-oxoquinazolin-2-yl group functioned as the B-ring) were markedly more cytotoxic than compounds 6a-s (in which 4-oxoquinazolin-2-yl group functioned as the A-ring), based on their IC50 values to inhibit proliferation. Compound 3f was found as the most potent among 38 analogues and the mechanism of its cytotoxicity was investigated. Flow cytometry indicated that HCT-116 cells treated with compound 3f resulted in a dose-dependent accumulation of cells in the sub-G1 phase, which is representative of apoptotic cells. Subsequent assays (including Annexin V-FITC/PI, AO-EB, MitoSOX (TM) Red and JC-1 staining) confirmed that 3f exposure induced apoptosis in HCT-116 cells. Immunoblotting analysis indicated that cellular exposure to 3f increased the cleavage of PARP1 and caspases 3, 7, and 9. Taken together, this novel chalcone analogue has a cytotoxic effect on cultured cancer cell-lines that is likely mediated by inducing apoptosis via the mitochondrial death pathway.

The first total synthesis of a marine natural product, exigurin, has been accomplished in 13 steps starting from (+)-menthone. The key intermediate (-)-10-epi-axisonitrile-3 was prepared by stereoselective intramolecular cyclopropanation followed by a cyclopropane ring opening reaction by the azide anion. The bioinspired Ugi reaction of (-)-10-epi-axisonitrile-3, formaldehyde, sarcosine and methanol successfully constructed the target exigurin in which its terpene and amino acid units were linked through an amide bond.

Computed Properties of C8H18O3. I found the field of Biochemistry & Molecular Biology; Chemistry very interesting. Saw the article 4H-Benzo[d][1,3]oxazin-4-ones and Dihydro Analogs from Substituted Anthranilic Acids and Orthoesters published in 2019.0, Reprint Addresses Bunce, RA (corresponding author), Oklahoma State Univ, Dept Chem, Stillwater, OK 74078 USA.. The CAS is 78-39-7. Through research, I have a further understanding and discovery of 1,1,1-Triethoxyethane.

A one-pot route to 2-alkyl and 2-aryl-4H-benzo[d][1,3]oxazin-4-ones (also known as 4H-3,1-benzoxazin-4-ones) has been developed and studied. The method involves the reaction of aryl-substituted anthranilic acids with orthoesters in ethanol catalyzed by acetic acid. Additionally, we have also investigated the reaction under microwave conditions. Not all of the substrates were successful in yielding the target heterocycles as some of the reactions failed to undergo the final elimination. This process led to the isolation of (+/-)-2-alkyl/aryl-2-ethoxy-1,2-dihydro-4H-benzo[d][1,3]oxazin-4-ones. The formation of the dihydro analogs correlated with the electron density on the aromatic ring: Electron-donating groups favored the 4H- benzo[d][1,3]oxazin-4-ones, while electron-withdrawing groups tended to favor the dihydro product. Substituting a pyridine ring for the benzene ring in the substrate acid suppressed the reaction.

Hsp90, as a key molecular chaperone, plays an important role in modulating the activity of many cell signaling proteins and is an attractive target for anticancer therapeutics. Herein, we report the discovery of N-pyridoyl-Delta(2)-pyrazoline analogs as novel Hsp90 inhibitors by integrated approaches of drug design, organic synthesis, cell biology, and qualitative proteomic analysis. Novel chemical compounds were designed and optimized in the adenosine triphosphate-binding site of Hsp90; lead optimized compounds were found to have significant interactions with Asp93 and other amino acids crucial for Hsp90 inhibition. The designed compounds were synthesized by a two-step procedure; different aromatic aldehydes were reacted with various acetophenones to form substituted 1,3-diphenyl-prop-2-enones (Ic-Io), which upon reaction with isonicotinic acid hydrazide in the presence of glacial acetic acid form N-pyridoyl-Delta(2)-pyrazoline compounds (PY1-PY13). Compounds PY3, PY2, and PY1 were identified as potential leads amongst the series, with promising anticancer activity against human breast cancer and melanoma cells, and the ability to inhibit Hsp90 similar to radicicol by drug-affinity responsive target stability proteomic analysis in a whole-cell assay.

The anticancer activity of chalcones and their analogs is the most important biological activity of them among their broad spectrum of their biological activity. In this investigation, we performed quantitative structure-activity relationship (QSAR) modeling of the anticancer activity of 134 chalcones and their analogs against MCF-7 human breast cancer cell lines using Monte Carlo method. QSAR models were calculated by CORAL software and optimal descriptors were calculated with SMILES and hydrogen suppressed molecular graph (HSG). The total dataset split into training, invisible training, calibration, and validation set randomly. Analysis of three probes of the Monte Carlo optimization with three random splits was done. Results from three random splits displayed robust, very simple, predictable, and reliable models for training, invisible training, calibration, and validation set with the correlation coefficient (R-2) of 0.8142-0.8244, 0.8244-0.8699, 0.8125-0.8627 and 0.8290-0.8686 respectively. As a result, the obtained models help to identify the hybrid descriptors for the increase and the decrease of anticancer activity of chalcones against MCF-7 human breast cancer cell lines. This simple QSAR model can be used for prediction of log IC50 of numerous chalcone derivatives against breast cancer cell. (C) 2019 Elsevier B.V. All rights reserved.

Axially chiral anilide compounds are an emerging but scarcely investigated class of stereogenic molecules with potential applications as biologically active scaffolds. Because of the lower rotation barriers, the synthesis of these compounds is a challenging task. Furthermore, the status of the limited structure type of chiral anilide constrains the latent capacity of the C-N axis as a chiral source in the application of asymmetric synthesis. Herein, we disclose an efficient protocol for the construction of the rationally designed axially chiral phosphamides via atroposelective N-allylic alkylation reaction of MBH carbonates and phosphamides. The simple hydroquinidine catalyst proves to be most efficient in this artroposelective strategy, delivering the desired axially chiral phosphamides in good yields and high enantioselectivities. In addition, a phosphamide compound, which contains both P-stereogenic center and C-N axial chirality, can be obtained by this method through a kinetic resolution process. Because of the large steric diaryl phosphoryl group, the synthesized axially chiral anilide has a large rotational barrier. As a demonstration, current studied axially chiral ortho-iodine substituted phosphamides could act as efficient chiral hypervalent iodine(III) catalysts for the asymmetric oxidative dearomatization of phenols. Moreover, a speculative model, which can explain the enantiocontrol, was proposed based on the experimental observation and theoretical calculation.

Olefin aminations are important synthetic technologies for the construction of aliphatic C-N bonds. Here we report a catalytic protocol for olefin hydroamidation that proceeds through transient amidyl radical intermediates that are formed via proton-coupled electron transfer (PCET) activation of the strong N-H bonds in N-alkyl amides by an excited-state iridium photocatalyst and a dialkyl phosphate base. This method exhibits a broad substrate scope, high functional group tolerance, and amenability to use in cascade polycyclization reactions. The feasibility of this PCET protocol in enabling the intermolecular anti-Markovnikov hydroamidation reactions of unactivated olefins is also demonstrated.

A novel strategy for the synthesis of delta-thiolactones from inexpensive and readily available gamma-unsaturated esters has been developed. This strategy incorporates a radical acyl thiol-ene reaction as the key C-S bond forming step. Cyclization is achieved via a Steglich-type thiolactonization of 5-mercaptopentanoic acids. We report the facile and scalable synthesis of delta-thiolactones in moderate to good yield under mild reaction conditions with tolerance for a range of functional groups.
