An I2/KOH synergistically promoted direct ring-opening aroylation of benzothiazoles with aryl ketones has been discovered. Aryl ketones were seen to act as carbonyl sources to construct 2-acylbenzothiazoles. This reaction could provide an example for the convergent integration of self-labor domino sequences based on an in situ cross-trapping strategy.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms.In my other articles, you can also check out more blogs about 2879-20-1name: 1-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)ethanone.

Cathepsin X is a cysteine carboxypeptidase that is involved in various physiological and pathological processes. In particular, highly elevated expression and activity of cathepsin X has been observed in cancers and neurodegenerative diseases. Previously, we identified compound Z9 (1-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)-2-((4-isopropyl-4H-1,2,4-triazol-3-yl)thio)ethan-1-one) as a potent and specific reversible cathepsin X inhibitor. Here, we have explored the effects of chemical variations to Z9 of either benzodioxine or triazol moieties, and the importance of the central ketomethylenethio linker. The ketomethylenethio linker was crucial for cathepsin X inhibition, whereas changes of the triazole heterocycle did not alter the inhibitory potencies to a greater extent. Replacement of benzodioxine moiety with substituted benzenes reduced cathepsin X inhibition. Overall, several synthesized compounds showed similar or improved inhibitory potencies against cathepsin X compared to Z9, with IC50 values of 7.1 muM?13.6 muM. Additionally, 25 inhibited prostate cancer cell migration by 21%, which is under the control of cathepsin X.

Synthetic Route of 22013-33-8, In chemical reaction engineering, simulations are useful for investigating and optimizing a particular reaction process or system. 22013-33-8, Name is 2,3-Dihydrobenzo[b][1,4]dioxin-6-amine,introducing its new discovery.

A chemical genomic screen of an in-house library of small molecule heterocycles was carried out using Xenopus laevis embryos. This led to the identification of N-(4-chloro-5H-1,2,3-dithiazol-5-ylidene)-4-methoxyaniline (1c), which elicits loss of pigmentation in melanophores and the retinal pigment epithelium (RPE) of developing embryos, independent of the developmental stage of initial exposure. The phenotype was reversible, since pigmentation returned upon compound removal while analysis of neural crest cell markers (Pax7) and melanophore markers (Dct/Xtrp2) revealed that both neural crest precursors and fully differentiated melanophores were present in the dithiazole 1c treated embryos. A subsequent focused structure-activity relationship (SAR) study identified the more active dithiazole 4-benzyloxy-N-(4-chloro-5H-1,2,3-dithiazol-5-ylidene)-aniline (1l) and the need for a chlorine substituent at the dithiazole C-4 position. Both the initial chemical genomic screen and the focused SAR study highlighted the toxicity of (dithiazolylidene)aminoazines, and also of methoxyaniline (anisidine) analogues that hosted strong electron-withdrawing or electronegative substituents or acidic hydroxyl groups on the anisidine moiety. This study suggests that 1,2,3-dithiazoles can act as reversible melanin synthesis inhibitors, revealing a new biological activity for this class of compounds. The inhibition of melanin synthesis is medically relevant as a potential treatment for pigmentation disorders such as melasma.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Synthetic Route of 22013-33-8, you can also check out more blogs about22013-33-8

It had been reported that some dioxygenated rings fusing with the quinazoline scaffold could lead to new EGFR inhibitors. Based on this, several kinds of oxygenated alkane quinazoline derivatives were synthetized and evaluated as EGFR inhibitors. Their antiproliferative activities were tested against four cancer cell lines: A431, MCF-7, A549, and B16-F10. Most derivatives could counteract EGF-induced EGFR phosphorylation, and their potency was comparable to the reference compound Erlotinib. The size of the fused dioxygenated ring was crucial for the biological activity and the heptatomic ring derivative 19 showed potent in vitro inhibitory activity in the enzymatic assay as well as in the cellular assay.

The vanilloid receptor-1 (TRPV1 or VR1) is a member of the transient receptor potential (TRP) family of ion channels and plays a role in regulating the function of sensory nerves. A growing body of evidence demonstrates the therapeutic potential of TRPV1 modulators, particularly in the management of pain. As a result of our screening efforts, we identified (E)-3-(4-tert- butylphenyl)-N-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)acrylamide (1), an antagonist that blocks the capsaicin-induced and pH-induced uptake of 45Ca2+ in TRPV1-expressing Chinese hamster ovary cells with IC50 values of 17 ± 5 and 150 ± 80 nM, respectively. In this report, we describe the synthesis and structure-activity relationship of a series of N-aryl cinnamides, the most potent of which (49a and 49b) exhibit good oral bioavailability in rats (Foral = 39% and 17%, respectively).

A series of new acridines has been prepared by cyclodehydration of N-(2,3-dihydro-1,4-benzodioxin-6-yl)anthranilic acid in acidic media following classical procedures. All these compounds have in common a dioxygenated ring fused to the acridine. The tetracyclic system possesses a linear or angular structure formed by intramolecular cyclisation. The last ring and the substituent of the system modify, in an interesting way, the antitumor activity of acridines. Several of the studied compounds displayed significant cytotoxic activity (inhibition of L1210 and HT-29 cell proliferation). The most cytotoxic compound 13a, shows more activity than m-AMSA in inhibiting L1210 and HT-29 cell proliferation and this compound has been selected as a development candidate for further evaluation. The activity results also indicate that the new 11-O-substituted compounds are of considerable interest with high levels of cytotoxic activity. The angular or non-linear dioxinoacridine 10 was equiactive with the linear structure 7. Pentacyclic analogues (14 and 15) were more cytotoxic than the tetracyclic compounds (up to twofold).
