Popiolek, Lukasz published the artcileSynthesis and in vitro bioactivity study of new hydrazide-hydrazones of 5-bromo-2-iodobenzoic acid, Recommanded Product: 2,3-Dimethoxybenzaldehyde, the main research area is aryl hydrazone preparation antitumor antimicrobial lipophilicity renal adenocarcinoma; 769-P cell line; Antimicrobial activity; Antiproliferative activity; COX-2; HepG2 cell line; Hydrazide-hydrazone; MBC; MIC; MTT assay; Vero cell line.

In this study 14 novel hydrazide-hydrazones of 5-bromo-2-iodobenzoic acid (3-16) were synthesized on the basis of condensation reaction. The chem. structure of obtained derivatives was established on the basis of spectral data (1H NMR and 13C NMR) and the lipophilicity of synthesized mols. was determined with the use of RP-HPTLC chromatog. Synthesized hydrazide-hydrazones (3-16) were subjected to in vitro cytotoxicity assay and antimicrobial activity anal. against a panel of bacteria and fungi. Among newly synthesized derivatives (3-16), compound 5 was characterized by high, selective and the most diverse cytotoxicity to the cancer cell lines. Mols. 7 and 9 which were substituted with a nitro group in the Ph ring also exhibited very significant inhibitory effect in the tumor cells and they were very selective. Similarly, compound 13 showed high antiproliferative activity against both cancer cell lines (769-P, HepG2) with satisfactory selectivity. In turn, mol. 8 was characterized by lower inhibitory effect in tumor cells but high selectivity. Derivative 16 proved to be toxic mainly to 769-P cells plausibly by the inhibition of COX-2 mediated signalling pathway. In summary, the introduction of chloro substituent or nitro group to the mol. proved to be most advantageous, providing high cytotoxicity and selectivity to tumor cells. However, the presence of indole scaffold appeared to be responsible for COX-2 inhibitory effect. Some of synthesized hydrazide-hydrazones possessed also moderate antimicrobial activity against a panel of microorganisms.

Shi, Shuai published the artcileThree-component radical homo Mannich reaction, Recommanded Product: 4-Methoxy-N-methylaniline, the main research area is ester ketone amide gamma amino preparation; aldehyde ketone photochem homo Mannich amine thiol.

By employing a radical process, enolizable aldehydes were utilized as substrates in the three-component radical homo-Mannich reaction for the streamlined synthesis of γ-amino-carbonyl compounds. The electrophilic radicals were generated from thiols HSCHR1C(O)R2 (R1 = H, Me; R2 = Me, EtO, PhCH2O, 1-adamantyl, Et2N, etc.) via the desulfurization process facilitated by visible-light, and then added to the electron-rich double bonds of enamines, formed in-situ from aldehydes or ketones R3CH2C(O)R4 [R3 = H, Et, MeSCH2, Ph, PhCH2, etc., R4 = H; R3 = H, R4 = Ph, 3-FC6H4, etc.; R3R4 = (CH2)5, CH2CHPhCH2CH2, CH2N(CH2Ph)CH2CH2, etc.] and amines R5NHR6 [R5 = Me, R6 = H2C:CHCH2, PhCH2, cyclohexyl, etc.; R5 = PhCH2, R6 = PhCH2, EtO2CCH2, etc.; R5R6 = (CH2)4, CHPh(CH2)3, etc.] to provide the products I in a single step. The broad scope, mild conditions, high functional group tolerance, and modularity of this metal-free approach for the synthesis of complex tertiary amine scaffolds will likely be of great utility to chemists in both academia and industry.

Murugesan, Kathiravan published the artcileReductive amination using cobalt-based nanoparticles for synthesis of amines, SDS of cas: 1205-17-0, the main research area is cobalt based nanoparticle catalyst preparation; amine preparation; aldehyde amine reductive amination cobalt based nanoparticle catalyst; nitroarene aldehyde reductive amination cobalt based nanoparticle catalyst.

In this protocol, the preparation of carbon-supported cobalt-based nanoparticles as efficient and practical catalysts for synthesis of different kinds of amines by reductive aminations was described. Template synthesis of a cobalt-triethylenediamine-terephthalic acid metal-organic framework on carbon and subsequent pyrolysis to remove the organic template resulted in the formation of supported single cobalt atoms and nanoparticles. Applying these catalysts, structurally diverse benzylic, aliphatic and heterocyclic primary, secondary and tertiary amines, including pharmaceutically relevant products, starting from inexpensive and easily accessible carbonyl compounds with ammonia, nitro compounds or amines and mol. hydrogen were synthesized. To prepare this cobalt-based catalyst took 26 h, and the reported catalytic reductive amination reactions could be carried out within 18-28 h.

Gao, Kai published the artcileNanoscale, automated, high throughput synthesis and screening for the accelerated discovery of protein modifiers, SDS of cas: 86-51-1, the main research area is protein modifier preparation combinatorial nanoscale; cyclic aromatic amidine aldehyde isocyanide Groebke Blackburn Bienayme reaction.

Hit finding in early drug discovery is often based on high throughput screening (HTS) of existing and historical compound libraries, which can limit chem. diversity, is time-consuming, very costly, and environmentally not sustainable. On-the-fly compound synthesis and in situ screening in a highly miniaturized and automated format has the potential to greatly reduce the medicinal chem. environmental footprint. Here, acoustic dispensing technol. has been used to synthesize a library in a 1536 well format based on the Groebke-Blackburn-Bienayme’ reaction (GBB-3CR) on a nanomole scale. The unpurified library was screened by differential scanning fluorimetry (DSF) and cross-validated using microscale thermophoresis (MST) against the oncogenic protein-protein interaction menin-MLL. Several GBB reaction products were found as μM menin binder, and the structural basis of the interactions with menin was elucidated by co-crystal structure anal. Miniaturization and automation of the organic synthesis and screening process can lead to an acceleration in the early drug discovery process, which is an alternative to classical HTS and a step towards the paradigm of continuous manufacturing
