The author of the article were Zhou, Yuanhang; Zhou, Chuhang; Zou, Yang; Jin, Yao; Han, Shidi; Liu, Qi; Hu, Xinping; Wang, Leqi; Ma, Yining; Liu, Yan. The article conveys some information:

Combination therapy has been proved to be an effective strategy to inhibit metastasis, however, its efficacy is always compromised by the poor delivery efficiency of drugs. In this study, multi pH-sensitive polymer-drug conjugate mixed micelles were fabricated by the self-assembly of PEOz-PLA-ace-Cur, a conjugate of curcumin (Cur) with poly(2-ethyl-2-oxazoline)-poly(D,L-lactide) (PEOz-PLA) through the linkage of the pH-cleavable acetal bond, and PEOz-PLA-imi-DOX, a conjugate of doxorubicin (DOX) with PEOz-PLA through the linkage of the pH-cleavable benzoic imine bond. The mixed conjugate micelles (PP-Cur/PP-DOX-Mix-PMs) with accurately and conveniently controlled mass ratio of the two drugs were demonstrated to have a small particle size (40-128 nm), high drug loading capacity and pH-dependent drug release behavior. Notably, PP-Cur5/PP-DOX1-Mix-PMs exhibited slower DOX release under physiol. conditions compared with PEOz-PLA-imi-DOX micelles, resulting in deeply reduced side effects in vivo. Furthermore, the mixed conjugate micelles showed synergistically enhanced inhibition of MDA-MB-231 cell growth and metastasis evidenced by the results of in vitro anti-invasion, wound healing and anti-migration assessment, and in vivo bioluminescence imaging in nude mice, and significant reduction of the side effects of DOX compared with dual drug phys. loaded polymeric micelles. Mechanistic studies demonstrated that the possible inhibitory mechanism of PP-Cur5/PP-DOX1-Mix-PMs on tumor metastasis could be assigned to their inhibition of the invasion, migration, intravasation and extravasation of tumor cells. In conclusion, the multi pH-sensitive polymer-drug conjugate mixed micelles with synergistically enhanced anti-tumor and anti-metastasis activity are potential candidates for safe and effective cancer combination therapy.3-Bromopropan-1-ol(cas: 627-18-9Related Products of 627-18-9) was used in this study.

Category: alcohols-buliding-blocksIn 2022 ,《C(sp3)-H oxygenation via alkoxypalladium(II) species: an update for the mechanism》 was published in Chemical Science. The article was written by Zhang, Shuaizhong; Zhang, Jinquan; Zou, Hongbin. The article contains the following contents:

In the present study of γ-C(sp3)-H acyloxylation of amine derivatives, a different mechanism was shown when tert-Bu hydroperoxide (TBHP) was used as an oxidant-namely, a bimetallic oxidative addition-oxo-insertion process. This catalytic model results in an alkoxypalladium(II) intermediate from which acyloxylation and alkoxylation products was formed. Exptl. and computational studies, including isolation of the putative post-oxo-insertion alkoxypalladium(II) intermediates, support this mechanistic model. D. functional theory revealed that the classical alkylpalladium(IV) oxidative addition pathway was higher in energy than the bimetallic oxo-insertion pathway. Further kinetic studies revealed second-order dependence on [Pd] and first-order on [TBHP], which was consistent with DFT anal. This procedure was compatible with a wide range of acids and alcs. for γ-C(sp3)-H oxygenation. Preliminary functional group transformations of the products underscore the great potential of this protocol for structural manipulation.

Quality Control of 5-Hexen-1-olIn 2021 ,《Oxidative additions of alkynyl/vinyl iodides to gold and gold-catalyzed vinylation reactions triggered by the MeDalphos ligand》 was published in Chemical Science. The article was written by Rodriguez, Jessica; Tabey, Alexis; Mallet-Ladeira, Sonia; Bourissou, Didier. The article contains the following contents:

The hemilabile Ad2P(o-C6H4)NMe2 ligand promotes fast, quant. and irreversible oxidative addition of alkynyl and vinyl iodides to gold. The reaction is general. It works with a broad range of substrates of various electronic bias and steric demand, and proceeds with complete retention of stereochem. from Z and E vinyl iodides. Both alkynyl and vinyl iodides react faster than aryl iodides. The elementary step is amenable to catalysis. Oxidative addition of vinyl iodides to gold and π-activation of alkenols (and N-alkenyl amines) at gold have been combined to achieve hetero-vinylation reactions. A number of functionalized heterocycles, i.e. tetrahydrofurans, tetrahydropyrans, oxepanes and pyrrolidines were obtained thereby (24 examples, 87% average yield). Taking advantage of the chemoselectivity for vinyl iodides over aryl iodides, sequential transformations involving first a hetero-vinylation step and then a C-N coupling, a C-C coupling or an heteroarylation were achieved from a vinyl/aryl bis-iodide substrate. The results came from multiple reactions, including the reaction of 5-Hexen-1-ol(cas: 821-41-0Quality Control of 5-Hexen-1-ol)

The article contains the following contents:

Malaria remains one of the major health problems worldwide. The increasing resistance of Plasmodium to approved antimalarial drugs requires the development of novel antiplasmodial agents that can effectively prevent and/or treat this disease. Based on the structure of Gamhepathiopine, a 2-tert-butylaminothieno[3,2-d]pyrimidin-4(3H)-one hit, active on the sexual and asexual stages of the parasite and thanked for the introduction of various substituents at position 4 of the thienopyrimidine core e.g., I by nucleophilic aromatic substitution and pallado-catalyzed coupling reactions, a series of 4-substituted thieno[3,2-d]pyrimidines were identified as displaying in vitro activities against both the erythrocytic stage of P. falciparum and the hepatic stage of P. berghei. Among the 28 compounds evaluated, the chloro analog of Gamhepathiopine showed good activity against the erythrocytic stage of P. falciparum, moderate toxicity on HepG2, and better activity against hepatic P. berghei parasites, compared to Gamhepathiopine.

《Selective uni- and bidirectional homologation of diborylmethane》 was written by Blair, Daniel J.; Tanini, Damiano; Bateman, Joseph M.; Scott, Helen K.; Myers, Eddie L.; Aggarwal, Varinder K.. Recommanded Product: Bis[(pinacolato)boryl]methaneThis research focused onuni bidirectional homologation diborylmethane; bis boronic ester preparation reactivity. The article conveys some information:

Diborylmethane can be homologated uni- and bidirectionally by using enantiomerically pure lithium-stabilized carbenoids to give 1,2- and 1,3-bis(boronic esters), resp., in good yield and with excellent levels of enantio- and diastereoselectivity. The high sensitivity of the transformation to steric hindrance enables the exclusive operation of either manifold, effected through the judicious choice of the type of carbenoid, which can be a sparteine-ligated or a diamine-free lithiated benzoate/carbamate. The scope of the 1,2-bis(boronic esters) so generated is complementary to that encompassed by the asym. diboration of alkenes, in that primary-secondary and primary-tertiary 1,2-bis(boronic esters) can be prepared with equally high levels of selectivity and that functional groups, such as terminal alkynes and alkenes, are tolerated. Methods for forming C2-sym. and non-sym. anti and syn 1,3-bis(boronic esters) are also described and represent a powerful route towards 1,3-functionalized synthetic intermediates.
