We recently discovered that 5, 8-O-dimethyl acylshikonin derivatives displayed the selectivity towards MCF-7 and no toxicity to normal cells. Herein, a series of the corresponding 6-isomers of 5, 8-O-dimethyl acylshikonin derivatives were synthesized starting from shikonin. In vitro evidence of the cytotoxicities indicated that most of thecompounds were more active than or comparative to shikonin and retained the selectivity against MCF-7, MDA-MB-231 besides no toxicity in the normal cells. Also, in vivo anticancer activity of the positional isomers 5p, 6c further showed that 6-isomers of 5, 8-O-dimethyl acylshikonin derivatives were more active than their corresponding 2-isomers. Thus, we may conclude that the position of the side chain of shikonin attached to 5,8-dimethoxy -1,4-naphthoquinone is associated with the antitumor activity.

Functionally selective G protein-coupled receptor ligands are valuable tools for deciphering the roles of downstream signaling pathways that potentially contribute to therapeutic effects versus side effects. Recently, we discovered both Gi/o-biased and beta-arrestin2-biased D2 receptor agonists based on the Food and Drug Administration (FDA)-approved drug aripiprazole. In this work, based on another FDA-approved drug, cariprazine, we conducted a structure-functional selectivity relationship study and discovered compound 38 (MS1768) as a potent partial agonist that selectively activates the Gi/o pathway over beta-arrestin2. Unlike the dual D2R/D3R partial agonist cariprazine, compound 38 showed selective agonist activity for D2R over D3R. In fact, compound 38 exhibited potent antagonism of dopamine-stimulated beta-arrestin2 recruitment. In our docking studies, compound 38 directly interacts with S1935.42 on TM5 but has no interactions with extracellular loop 2, which appears to be in contrast to the binding poses of D2R beta-arrestin2-biased ligands. In in vivo studies, compound 38 showed high D2R receptor occupancy in mice and effectively inhibited phencyclidine-induced hyperlocomotion.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 82771-60-6 is helpful to your research. Electric Literature of 82771-60-6

New research progress on 1612-65-3 in 2021. Electric Literature of 1612-65-3, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst.

The reaction of cotarnine and acyl/aryl ketones in ?green? solvents provides an efficient approach to an array of privileged 1,2,3,4-tetrahydroisoquinolines in excellent yields by metal-free activation of C(sp3)?H bonds. This one-pot procedure takes place under base-free conditions at room temperature, and tolerates a wide range of functionalities. The reaction is highly chemoselective, can be performed on a multi-gram scale, and pure products are isolated by simple filtration without workup. Interestingly, the complementary two-step procedure from cotarnine halide salts gives the Mannich products in good yields. The scope was elaborated to 9-bromocotarnine salts to access a range of 9-bromonoscapine-derived analogues. The methodology has been developed considering the structural similarity of cotarnine derivatives to noscapinoids, which represent an emerging class of microtubule-modulating anticancer agents.

A transition-metal-free protocol for the redox-neutral light-induced decarboxylative coupling of carboxylic acids with (hetero)aromatic nitriles at ambient temperature is presented. A broad scope of acids and nitriles is accepted, and alcohols can be coupled in a similar fashion through their oxalate half esters. Various inexpensive sources of UV light and even sunlight can be used to achieve this C-C bond formation proceeding through a free radical mechanism.
