Palladium-catalyzed C–P bond activation of aroyl phosphine oxides without the adjacent “anchoring atom”
Chen, Xingyu,Liu, Xiaoyan,Zhu, Hong,Wang, Zhiqian
, (2021/01/14)
A novel palladium-catalyzed decarbonylation of aroyl phosphine oxides to prepare phosphine oxides from carboxylic acids is developed. Without the adjacent “anchoring atom”, the challenging C–P bond activation is achieved in high selectivity. The disclosure of this reaction provides a new example of C–P bond activation and helps to extend the understanding of the property of C–P bond.

Minimalistic 2-(oxazolinyl)-phenols substituted with different electron-donating and -withdrawing groups as well as 1,2,5-chalcogenadiazole-annulated derivatives thereof were synthesized and investigated in regard to their emission behavior in solution as well as in the solid state. Depending on the nature of the incorporated substituent and its position, emission efficiencies were increased or diminished, resulting in AIE or ACQ characteristics. Single-crystal analysis revealed J- and H-type packing motifs and a so-far undescribed isolation of ESIPT-based fluorophores in the keto form.

[Figure not available: see fulltext.] Acyl derivatives of aziridine-2-carboxylic acid have been synthesized and tested as PDIA1 inhibitors. Calculations of charge value and distribution in aziridine ring system and some alkylating agents were performed. For the first time was found that acyl derivatives of aziridine-2-carboxylic acid are weak to moderately active PDIA1 inhibitors.

Paragraph 0126; 0150-0153, (2019/02/04)
The invention relates to amide prodrug compounds of novel kinase inhibitors. The prodrugs are characterized in that amino of original drugs is subjected to amidation modification, so that bioavailability of the original drugs in vivo is significantly improved. The invention further relates to pharmaceutical composition containing the prodrugs and a method for treating cancer or other cell proliferative abnormal diseases by the prodrugs and the pharmaceutical composition.

Targeting CCR2 and CCR5 receptors is considered as promising concept for the development of novel antiinflammatory drugs. Herein, we present the development of the first probe-dependent positive allosteric modulator (PAM) of CCR5 receptors with a 2-benzazepine scaffold. Compound 14 (2-isobutyl-N-({[N-methyl-N-(tetrahydro-2H-pyran-4-yl)amino]methyl}phenyl)-1-oxo-2,3-dihydro-1H-2-benzazepine-4-carboxamide) activates the CCR5 receptor in a CCL4-dependent manner, but does not compete with [3H]TAK-779 binding at the CCR5. Furthermore, introduction of a p-tolyl moiety at 7-position of the 2-benzazepine scaffold turns the CCR5 PAM 14 into the selective CCR2 receptor antagonist 26b. The structure affinity and activity relationships presented here offer new insights into ligand recognition by CCR2 and CCR5 receptors.

A naturally occurring isoquinolinone alkaloid marinamide and its methyl ester were synthesised from phthalic anhydride over eight steps in 46% and 52% overall yield. The key intermediate methyl 2-(1-benzyl-1H-pyrrole-2-carbonyl) benzoate was synthesised from the acid chloride of mono methyl phthalate and 1-benzyl-1H-pyrrole catalysed by Zinc oxide under solvent-free conditions at room temperature.
