I found the field of Chemistry very interesting. Saw the article Preparation of some chromeno[4,3-d]pyrido[1,2-a]pyrimidine derivatives by ultrasonic irradiation using NiFe2O4@SiO2 grafted di(3-propylsulfonic acid) nanoparticles published in 2021. Category: indole-building-block, Reprint Addresses Khalaj, M (corresponding author), Islamic Azad Univ Buinzahra, Dept Chem, Buinzahra Branch, Buin Zahra, Iran.. The CAS is 120-14-9. Through research, I have a further understanding and discovery of 3,4-Dimethoxybenzaldehyde

NiFe2O4@SiO2 grafted di(3-propylsulfonic acid) was prepared by a facile method and characterized using XRD, FT-IR, SEM-EDX, TGA, and BET techniques. The XRD pattern shows the characteristic peaks of the cubic structure for NiFe2O4. The presence of sulfonic acid groups was confirmed by FT-IR analysis. The catalyst was used for the preparation of chromeno[4,3-d]pyrido[1,2-a]pyrimidine derivatives via the three-component condensation reaction of 4-hydroxycoumarin, aldehydes, and 2-aminopyridines under US irradiation. The effects of solvent, temperature, and catalyst dosage on product formation under the reaction conditions were investigated. The simple procedure, good yields, short reaction times, and catalyst recovery are some of the key advantages of this method.

With the aim of expanding the scope of SAR on piperlongumine (PL), a naturally occurring anticancer molecule, we have designed a novel hybrid molecule bearing 3,4-dihydroisoquinolin-1(2H)-one and trans-cinnamic acids. The structure, based on hybridization strategy, is used for hybridization of naturally occurring scaffolds. We have synthesized 14 hybrid molecules by coupling 3,4-dihydroisoquinolin-1(2H)-one core with cinnamic acids using the mix anhydride approach. The newly synthesized inhibitors were evaluated for cell viability against breast cancer MCF-7 and cervical cancer HeLa cell lines. Furthermore, the active compounds were screened for their potential in breast cancer MDA-MB-231, cervical cancer C33A cell lines, prostate cancer DU-145, PC-3, and normal VERO cells. From the series, compound 10g was seen to inhibit MCF-7 cell growth significantly with GI(50) < 0.1 mu M along with growth inhibition in MDA-MB-231 (GI(50) = 20 mu M) and C33A (GI(50) = 3.2 mu M). While the inhibitor 10i inhibits MCF-7 breast cancer cell growth GI(50) = 3.42 mu M along with inhibition of cell growth in MDA-MB-231 (GI(50) = 30 mu M), HeLa (GI(50) = 7.67 mu M), C33A (GI(50) = 13 mu M), DU-145 (GI(50) = 6.45 mu M), PC-3 (GI(50) = 8.68 mu M), and VERO (GI(50) = 2.93 mu M), respectively. Furthermore, molecular docking study demonstrated these compounds could bind tightly to the colchicine domain of tubulin through a network of favorable steric and electrostatic interactions and thus act as a tubulin polymerization inhibitor.

SAR studies on bicalutamide, enobosarm and enzalutamide analogues, functionalised with polyfluorinated groups, is presented. Among the novel bicalutamide and enobosarm derivatives synthesised, several displayed significantly improved in vitro anticancer activity, with IC50 values in the low micromolar range against four different prostate cancer cell lines (LNCaP, VCaP, DU-145 and 22Rv1), showing up to 48-fold increase in comparison with the parent structures. In particular, SF5 enobosarm analogues were found to be most potent compounds, full AR antagonists and with favourable ADME properties. The most promising compound (48a) was evaluated for its in vivo efficacy in PC xenograft mouse model (22Rv1) with results comparable to the standard-of-care docetaxel.

InhA or enoyl-acyl carrier protein reductase of Mycobacterium tuberculosis (mtInhA), which controls mycobacterial cell wall construction, has been targeted in the development of antituberculosis drugs. Previously, our in silico structure-based drug screening study identified a novel class of compounds (designated KES4), which is capable of inhibiting the enzymatic activity of mtInhA, as well as mycobacterial growth. The compounds are composed of four ring structures (A-D), and the MD simulation predicted specific interactions with mtInhA of the D-ring and methylene group between the B-ring and C-ring; however, there is still room for improvement in the A-ring structure. In this study, a structure-activity relationship study of the A-ring was attempted with the assistance of in silico docking simulations. In brief, the virtual chemical library of A-ring-modified KES4 was constructed and subjected to in silico docking simulation against mtInhA using the GOLD program. Among the selected candidates, we achieved synthesis of seven compounds, and the bioactivities (effects on InhA activity and mycobacterial growth and cytotoxicity) of the synthesized molecules were evaluated. Among the compounds tested, two candidates (compounds 3d and 3f) exhibited superior properties as mtInhA-targeted anti-infectives for mycobacteria than the lead compound KES4.

Two new series of diethyl 2-[2-(substituted-2-oxo-1,2-dihydroquinolin-4-yl)hydrazono]-succinates 6a-g and 1-(2-oxo-1,2-dihydroquinolin-4-yl)-1H-pyrazoles 7a-f have been designed and synthesized. The structures of the synthesized compounds were proved by IR, mass, NMR (2D) spectra and elemental analyses. The target compounds were evaluated for their in vitro cytotoxic activity against 60 cancer cell lines according to NCI protocol. Consequently, seven compounds were further examined against the most sensitive cell lines, leukemia CCRFCEM, and MOLT-4. 5-Amino-1-(6-bromo-2-oxo-1,2-dihydroquinolin-4-yl)-1H-pyrazole-3,4-dicarbonitrile (7f) was the most active product, with IC50= 1.35 uM and 2.42 uM against MOLT-4 and CCRF-CEM, respectively. Also, it showed a remarkable inhibitory activity compared to erlotinib on the EGFR TK with IC50 = 247.14 nM and 208.42 nM, respectively. Cell cycle analysis of MOLT-4 cells treated with 7f showed cell cycle arrest at G2/M phase (supported by Caspases, BAX and Bcl-2 studies) with a significant pro-apoptotic activity as indicated by annexin V-FITC staining. Moreover, the docking study indicated that both the pyrazole moiety and the quinolin-2-one ring showed good fitting into EGFR (PDB code: 1M17). In order to interpret SAR of the designed compounds, and provide a basis for further optimization, molecular docking of the synthesized compounds to known EGFR inhibitors was performed. The study illustrated the effect of several factors on the compounds’ activity.

The chemical class of benzotrifluoride derivatives is widely used in active ingredients of various commercial products, such as pharmaceuticals, pesticides, herbicides, and crop protection agents. Past studies have shown that some benzotrifluorides are not stable under UV irradiation in water and convert into benzoic acids due to C-F bond hydrolysis. It was also observed, but never systematically studied, that the ring substituents play an important role on the direct photochemical reactivity of the CF3 moiety. In the present work, we explore the structure-reactivity relationship between ring substituent and direct photodefluorination for 16 different substituents, by determining fluoride production rates, quantum yields, and half-lives, and found that strong electron-donating groups enhance the reactivity toward hydrolysis. In addition, flufenamic acid, travoprost, dutasteride, cyflumetofen, flutoanil, and teriflunomide were also examined, finding that their direct photochemical reactivity could be qualitatively predicted based on their ring substituents. We provide here a tool to evaluate the environmental persistence of benzotrifluoride contaminants, as well as to design more photodegradable new active ingredients.

A practical method for the synthesis of phenyl enol ethers is reported. The combination of a gold(I) catalyst and potassium carbonate selectively mediates the addition of phenols to propargylic alcohols/amines in a chemo-, regio-, and stereoselective fashion in high yield. The resulting enol ethers are formed exclusively with a Z-configuration and can be obtained from a wide array of phenols and propargylic alcohols or amines with the reaction showing excellent functional group tolerance.

Prenylated chalcones xanthohumol (1) and 2 ‘-hydroxy-3,4,4 ‘-trimethoxy-6 ‘-O-prenyl chalcone (2) were synthesized through the Claisen-Schmidt condensation, O-prenylation, and Claisen rearrangement and deprotection respectively, using phloroglucinol and appropriate benzaldehydes as starting materials. Based on the Mannich reaction of prenylated chalcone 1 or 2 with various secondary amines and formaldehyde in acid alcohol solvent, 10 novel prenylated chalcone Mannich base derivatives 3a-3e and 4a-4e were synthesized. Furthermore, all synthetic compounds were evaluated for antiproliferative activities in vitro against four human cancer cell lines (Aspc-1, SUN-5, HepG-2, and HCT-116) by MTT assay. The results showed that most of them exhibit moderate to good antiproliferative activities against the four human cancer cells with IC50 values of 2.52 to 47.67 mu M.
