Semi-synthesis and anti-tumor activity of 5,8-O-dimethyl acylshikonin derivatives

A set of twenty-two 5,8-O-dimethyl acylshikonin derivatives were designed and synthesized starting from shikonin. The cell-based investigation demonstrated that these dimethylated derivatives were less active than or equally effective to shikonin. However, the selective cytotoxicities toward MCF-7 were found among these derivatives, together with no toxicity in the normal cell. Furthermore, compounds 3f, 3p, 3r were subjected to KM mice suffering from S-180 carcinoma subcutaneously, which possessed more potent than Fluorouracil, a typical anticancer drug used clinically. So we may conclude that the modification to the mother nucleus of shikonin via the methylation is an available approach to acquiring anti-tumor agents with higher selectivity and lower toxicity.

Ortho-Quinone methides as key intermediates in cascade heterocyclizations

Development of new methods of heterocyclic synthesis is still a topical issue. In this connection, the trend related to the use of highly reactive o-quinone methides for the synthesis and functionalization of heterocycles appears rather promising. Since most of o-quinone methides are unstable, the choice of precursors and generation conditions is highly important for subsequent transformations involving them. Various methods of generation of o-quinone methides and cascade hetero- cyclizations in which the formation of these compounds is a key step are surveyed in the review. The trends of using o-quinone methides in the synthesis of various heterocycles are analyzed and the heterocyclization reactions involving these compounds are classified.

Structure-activity relationship of a series of inhibitors of monoacylglycerol hydrolysis – Comparison with effects upon fatty acid amide hydrolase

A series of 32 heterocyclic analogues based on the structure of 2-arachidonoylglycerol (2-AG) were synthesized and tested for their ability to inhibit monoacylglycerol lipase and fatty acid amide hydrolase activities. The designed compounds feature a hydrophobic moiety and different heterocyclic subunits that mimic the glycerol fragment. This series has allowed us to carry out the first systematic structure-activity relationship study on inhibition of 2-AG hydrolysis. The most promising compounds were oxiran-2-ylmethyl (5Z,8Z,11Z,14Z)-icosa-5,8,11,14-tetraenoate (1) and tetrahydro-2H-pyran-2- ylmethyl (5Z,8Z,11Z,14Z)-icosa-5,8,11,14-tetraenoate (5). They inhibited cytosolic 2-oleoylglycerol (2-OG) hydrolysis completely (IC50 values of 4.5 and 5.6 muM, respectively). They also blocked, albeit less potently, 2-OG hydrolysis in membrane fractions (IC50 values of 19 and 26 muM, respectively) and anandamide hydrolysis (IC50 values of 12 and 51 muM, respectively). These compounds will be useful in delineating the importance of the cytosolic hydrolytic activity in the regulation of 2-AG levels and, hence, its potential as a target for drug development.

Methyllycaconitine analogues have mixed antagonist effects at nicotinic acetylcholine receptors

Bicyclic analogues of methyllycaconitine (MLA), such as 12, have been synthesised that incorporate the C1-OMe substituent present in the natural product. Electrophysiology experiments using Xenopus oocytes expressing nicotinic acetylcholine receptors (nAChRs) were conducted on these analogues and a related tricyclic analogue 2. The most potent compound, 2, was an antagonist at all receptors studied but displayed different antagonist effects at each receptor subtype. This study more clearly defines the biological effects of MLA analogues at nAChRs and demonstrates that these analogues are not selective ligands for the alpha7 nAChR subtype.

Palladium-Catalyzed Directed C(sp3)-H Arylation of Saturated Heterocycles at C-3 Using a Concise Optimization Approach

Saturated heterocycles, such as THFs, pyrrolidines, piperidines and THPs, are essential components of many biologically active compounds. Examples of C-H functionalization on these important ring systems remain scarce, especially at unactivated positions. Here we report the development of conditions for the palladium-catalyzed stereoselective C(sp3)-H arylation at unactivated 3-positions of 5- and 6-membered N- and O-heterocycles with aminoquinoline directing groups. Subtle differences in substrate structures altered their reactivity significantly; and different conditions were required to achieve high yields in each case. Successful conditions were developed using a short empirical optimization approach to cover reaction space with a limited set of variables. Excellent cis-selectivity was achieved in all cases, except for the THP substrate where minor trans-products were formed through a different palladacyclic intermediate. Here, differences in reactivity and selectivity with other directing groups were examined.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 87392-05-0, and how the biochemistry of the body works.Computed Properties of C5H8O3
