89364-31-8, Name is Tetrahydrofuran-3-carboxylic acid, belongs to tetrahydrofurans compound, is a common compound. Recommanded Product: 89364-31-8In an article, once mentioned the new application about 89364-31-8.

A series of novel beta-hydroxyisovalerylshikonin analogues bearing oxygen-containing substituents at the side-chain hydroxyl of shikonin were designed and synthesized. The cytotoxicities of these compounds were evaluated in vitro against multi-drug resistant (MDR) cell lines DU-145 and HeLa. Most compounds exhibited significant inhibitory activity on both cell lines. The structure-activity relationship showed the analogues with ether substituents displayed the most potent antitumour activity and selective cytotoxicity towards DU-145. Among the compounds with ether substituents, increasing the steric hindrance in the carbon bearing beta-hydroxyl or replace the beta-hydroxyl with acetoxy or methoxy would lead to the decline of cytotoxicity.

Podophyllotoxin has been extensively used as a lead agent in the development of new anticancer drugs. On the basis of the previously reported simplified 4-aza-2,3-didehydro podophyllotoxin analogues, we implemented a bioisosteric replacement of the methylenedioxybenzene subunit with a pyrazole moiety to afford tetracyclic dihydropyridopyrazoles. Libraries of these structurally simple analogues are prepared by a straightforward one-step multicomponent synthesis and demonstrated to display antiproliferative properties in a number of human cancer cell lines. These new heterocycles potently induce apoptosis in cancerous Jurkat cells even after a short 24 h exposure. In contrast, no apoptosis is detected in primary lymphocytes under the same treatment conditions. The ease of synthesis and encouraging biological activities make the presented library of dihydropyridopyrazoles promising new leads in anticancer drug design.

The ozonolysis of cyclohexene is an important model system for understanding the more complex reaction of O3 with monoterpenes; however, many previous studies have come to qualitatively different conclusions about the composition of the secondary organic aerosol (SOA) formed in this system. In the present study, the composition of the SOA produced by cyclohexene ozonolysis in the absence of seed aerosols has been investigated online and off-line using synchrotron-based thermal desorption/tunable vacuum ultraviolet photoionization time-of-flight aerosol mass spectrometry (TD-VUV-TOF-PIAMS) in conjunction with a custom-built smog chamber. On the basis of the molecular ions observed by mass spectrometry at 11.5 eV, it was found that dicarboxylic acids, dialdehydes, and cyclic anhydrides are the predominant low molecular weight components in the particle phase. The results also indicated that TD-VUV-TOF-PIAMS coupled with filter sampling is a potentially useful tool for the investigation of SOA composition both in the field and in the laboratory.
