Jiao, Peili;Wang, Yuxi;Mao, Beibei;Wang, Bingding;Zhong, Yi;Jin, Hongwei;Zhang, Lihe;Zhang, Liangren;Liu, Zhenming published 《Discovery of 2-(2-aminobenzo[d]thiazol-6-yl) benzo[d]oxazol-5-amine derivatives that regulated HPV relevant cellular pathway and prevented cervical cancer from abnormal proliferation》 in 2020. The article was appeared in 《European Journal of Medicinal Chemistry》. They have made some progress in their research.Computed Properties of C7H5N3O2S The article mentions the following:

Herein, virtual screening was performed and 2-(2-aminobenzo[d]thiazol-6-yl) benzo[d]oxazol-5-amine derivatives I (R¹ = H, NH₂; R² = H, NH₂, NHC(O)NHC₂H₅) were designed, synthesized as antineoplastic agents, and evaluated for their anti-tumor activities. Among them, the most promising compound I (R = R¹ = NH₂) (II) showed specific anti-proliferation ability against HeLa cells (IC₅₀ = 380 nM) as well as excellent inhibition of tumor growth in the HeLa xenograft model without inducing obvious side effects. It is interesting that compound II displayed significant inhibition against HPV18-pos. cervical cell lines (HeLa) but not for HPV16-pos. cervical cell lines (SiHa). Further study demonstrated that a low concentration of compound II could lead to a cell cycle blockage at the G1 phase and promote cell apoptosis slightly (8.77%). Compound II also exhibited transcription repression, especially those associated with the oncoprotein E7 cellular pathway like E7/Rb/E2F-1/DNMT1, which were essential in tumorigenesis. Proteomics anal. revealed that E7 might be degraded through E3 ubiquitin ligases, which aligned with decreasing expression of E7 following the treatment of compound II. Taken together, it indicated that compound II could be a promising potential agent for cervical cancer treatment. To complete the study, the researchers used 6-Nitrobenzo[d]thiazol-2-amine (cas: 6285-57-0) .

Quality Control of 2-((5-Nitrothiazol-2-yl)carbamoyl)phenyl acetate《Lipoic acid (LA) dose-dependently protects bone losses in the mandible of rats during the development of osteopenia by inhibiting oxidative stress and promoting bone formation》 was published in 2022. The authors were Radzki, Radoslaw Piotr;Bienko, Marek;Wolski, Dariusz;Oniszczuk, Tomasz;Radzka-Pogoda, Agnieszka;Polak, Pawel;Borzecki, Andrzej;Stasiak, Mateusz, and the article was included in《Biomedicine & Pharmacotherapy》. The author mentioned the following in the article:

Our study was carried out to evaluate the effect of lipoic acid (LA) on the densitometric properties, structure and mech. strength of the mandible of Wistar rats with developing osteopenia. The study used 42 sham-operated (SHO) and ovariectomized (OVX) rats. The OVX rats were randomly divided (n = 6) onto two controls treated s.c. with physiol. saline (OVX-PhS) and 17β-estradiol (OVX-E2), resp., and onto four exptl. OVX groups that received LA in the doses of 12.5, 25, 50 and 100 mg/kg/day for 28 days. The results demonstrated that the lack of estrogen brought about osteopenic bone changes, especially in the trabecular compartment. In addition, while the usage of LA in the doses of 12.5 and 25 LA had no effect in OVX rats, the dose of 100 effectively inhibited osteopenic changes of the mandible. This dose maintained structural, densitometric and mech. parameters at levels like that in the SHO and OVX-E2 groups by inhibiting the destructive influence of oxidative stress. Dose 50, however, was revealed to be the most effective. It not only inhibited atrophic changes and the influence of oxidative stress, but also stimulated the formation of mandibular bone tissue. Our results suggest that the administration of LA is effective in preventing atrophic changes in the mandibular bone tissue in conditions of ovarian hormone deficiency and suggest its potential in the therapy of osteoporosis. And 2-((5-Nitrothiazol-2-yl)carbamoyl)phenyl acetate (cas: 55981-09-4) was used in the research process.

Computed Properties of C12H9N3O5SIn 2021, Sun, Haiyan;Ou, Tong;Hu, Jianyang;Yang, Ziyi;Lei, Qifang;Li, Yuqing;Wang, Gang;Li, Yongpeng;Wu, Kai;Wang, Shupeng;Wu, Song published 《Nitazoxanide impairs mitophagy flux through ROS-mediated mitophagy initiation and lysosomal dysfunction in bladder cancer》. 《Biochemical Pharmacology (Amsterdam, Netherlands)》published the findings. The article contains the following contents:

Bladder cancer is one of the most common malignancy in the urinary tract with high recurrence and drug resistance in clinics. Alternative treatments from existing drugs might be a promising strategy. Nitazoxanide (NTZ), an FDA-approved antiprotozoal drug, has got increasingly noticed because of its favorable safety profile and antitumor potential, yet the effects in bladder cancer and underlying mechanisms remain poorly understood. Herein, we find that NTZ induces mitochondrial damage and mitophagy initiation through PINK1-generated phospho-ubiquitin(pS65-Ub) and autophagy receptor-mediated pathway even in the absence of Atg5/Beclin1. Meanwhile, NTZ inhibits lysosomal degradation activity, leading to mitophagy flux impairment at late stage. Mitochondrial reactive oxygen species (ROS) production is critical in this process, as eliminating ROS with N-acetylcysteine (NAC) efficiently inhibits PINK1 signaling-mediated mitophagy initiation and alleviates lysosomal dysfunction. Co-treatment with NTZ and autophagy inhibitor Chloroquine (CQ) to aggravate mitophagy flux impairment promotes NTZ-induced apoptosis, while alleviation of mitophagy flux impairment with ROS scavenger reduces cell death. Moreover, we also discover a similar signaling response in the 3D bladder tumor spheroid after NTZ exposure. In vivo study reveals a significant inhibition of orthotopic bladder tumors with no obvious systemic toxicity. Together, our results uncover the anti-tumor activities of NTZ with the involvement of ROS-mediated mitophagy modulation at different stages and demonstrate it as a potential drug candidate for fighting against bladder tumors.2-((5-Nitrothiazol-2-yl)carbamoyl)phenyl acetate (cas: 55981-09-4) were involved in the experimental procedure.

Name: 2-((5-Nitrothiazol-2-yl)carbamoyl)phenyl acetateIn 2021, Fahmy, Mennat-Elrahman Ahmed;Abdelaal, Amany Ahmed;Hassan, Soad Ismail;Shalaby, Maisa Ahmed;Ismail, Mousa Abdelgawad Mousa;Khairy, Rasha Ahmed;Badawi, Manal Abdelmaged;Afife, Adam Ashraf;Fadl, Hanaa Omar published 《Antiparasitic and immunomodulating effects of nitazoxanide, ivermectin and selenium on Cryptosporidium infection in diabetic mice.》. 《Revista brasileira de parasitologia veterinaria = Brazilian journal of veterinary parasitology : Orgao Oficial do Colegio Brasileiro de Parasitologia Veterinaria》published the findings. The article contains the following contents:

The present work aims to investigate the antiparasitic and the immunomodulating effects of nitazoxanide (NTZ) and ivermectin (IVC) alone or combined together or combined with selenium (Se), on Cryptosporidium infection in diabetic mice. The results revealed that the combined NTZ and IVC therapy achieved the highest reduction of fecal oocysts (92%), whereas single NTZ showed the lowest reduction (63%). Also, adding Se to either NTZ or IVC resulted in elevation of oocyst reduction from 63% to 71% and from 82% to 84% respectively. All treatment regimens, with the exception of NTZ monotherapy, showed a significant improvement in the intestinal histopathology, the highest score was in combined NTZ and IVC therapy. The unique results of immunohistochemistry in this study showed reversal of the normal CD4/CD8 T cell ratio in the infected untreated mice, however, following therapy it reverts back to a normal balanced ratio. The combined (NTZ+ IVC) treatment demonstrated the highest level of CD4 T cell expression. Taken together, NTZ and IVC combined therapy showed remarkable anti-parasitic and immunostimulatory effects, specifically towards the CD4 population that seem to be promising in controlling cryptosporidiosis in diabetic individuals. Further research is required to explore other effective treatment strategies for those comorbid patients.

Reference of 2-((5-Nitrothiazol-2-yl)carbamoyl)phenyl acetateIn 2022, Ferreira de Lima, Nayana;de Andrade Picanco, Guaraciara;Costa, Tatiane Luiza;Vinaud, Marina Clare published 《In vitro metabolic stress induced by nitazoxanide and flubendazole combination in Taenia crassiceps cysticerci》. 《Experimental Parasitology》published the findings. The article contains the following contents:

Taenia crassiceps is often used as exptl. model for T. solium cysticercosis studies. Currently cysticercosis antiparasitic treatment is based on albendazole and praziquantel which may present side effects and parasitic resistance. The search for other antiparasitic drugs is necessary. Nitazoxanide (NTZ) and flubendazole (FLB) are broad spectrum antiparasitic drugs that present anti-cysticercosis effect. Metabolic analyses help to determine the impact of these drugs on parasites. The aim of this study was to determine the impact on the production and excretion of organic metabolites in T. crassiceps cysticerci after in vitro exposure to NTZ and FLB, isolated or in combination. T. crassiceps cysticerci were culture in RPMI medium and exposed to 10 μg/mL of NTZ, 10 μg/mL of FLB or 10 μg/mL of NTZ +10 μg/mL of FLB. 24 h after exposure, the parasites were chromatog. analyzed to determine the impact of these drugs on glycolysis, homolactic fermentation, tricarboxylic acid cycle, fatty acids oxidation and proteins catabolism. It was possible to determine that the drugs combination induced greater metabolic impact on cysticerci in comparison to the isolated drugs exposure. The drugs combination induced gluconeogenesis, metabolic acidosis, increase in tricarboxylic acid cycle and in proteins catabolism. While the NTZ isolated exposure induced metabolic acidosis and protein catabolism and the FLB isolate exposure induced gluconeogenesis and protein catabolism. These results show that the combination of drugs with different modes of action increase the antiparasitic effect and may be indicated as alternative cysticercosis treatments. To complete the study, the researchers used 2-((5-Nitrothiazol-2-yl)carbamoyl)phenyl acetate (cas: 55981-09-4) .

Synthetic Route of C7H5N3O2SIn 2021, Giovannucci, Tatiana A.;Salomons, Florian A.;Haraldsson, Martin;Elfman, Lotta H. M.;Wickstroem, Malin;Young, Patrick;Lundbaeck, Thomas;Eirich, Jurgen;Altun, Mikael;Jafari, Rozbeh;Gustavsson, Anna-Lena;Johnsen, John Inge;Dantuma, Nico P. published 《Inhibition of the ubiquitin-proteasome system by an NQO1-activatable compound》. 《Cell Death & Disease》published the findings. The article contains the following contents:

Malignant cells display an increased sensitivity towards drugs that reduce the function of the ubiquitin-proteasome system (UPS), which is the primary proteolytic system for destruction of aberrant proteins. Here, we report on the discovery of the bioactivatable compound CBK77, which causes an irreversible collapse of the UPS, accompanied by a general accumulation of ubiquitylated proteins and caspase-dependent cell death. CBK77 caused accumulation of ubiquitin-dependent, but not ubiquitin-independent, reporter substrates of the UPS, suggesting a selective effect on ubiquitin-dependent proteolysis. In a genome-wide CRISPR interference screen, we identified the redox enzyme NAD(P)H:quinone oxidoreductase 1 (NQO1) as a critical mediator of CBK77 activity, and further demonstrated its role as the compound bioactivator. Through affinity-based proteomics, we found that CBK77 covalently interacts with ubiquitin. In vitro experiments showed that CBK77-treated ubiquitin conjugates were less susceptible to disassembly by deubiquitylating enzymes. In vivo efficacy of CBK77 was validated by reduced growth of NQO1-proficient human adenocarcinoma cells in nude mice treated with CBK77. This first-in-class NQO1-activatable UPS inhibitor suggests that it may be possible to exploit the intracellular environment in malignant cells for leveraging the impact of compounds that impair the UPS.6-Nitrobenzo[d]thiazol-2-amine (cas: 6285-57-0) were involved in the experimental procedure.

Alk. dyeing of polyester fabric can shorten the traditional dyeing process, save energy and water. It is an important direction of energy conservation and emission reduction But alk. dyeing has a higher requirement on the structural stability of dyes. With 2-amino-6-nitrobenzothiazole as diazo component and N-substituted aniline as coupling component, five disperse dyes containing different N-substituents were designed and synthesized. The dyeing properties of polyester fabric with disperse dyes under different NaOH concentrations (1-5 g/L) were tested. The relationship between dye structure and dyeing stability under basic dyeing conditions was discussed. The dyeing properties of dyes with different structures under acid and alkali conditions were compared. The results show that the hybrid dyes with Et and benzyl structure has good alkali resistance stability, acid and alkali dyeing condition does not have obvious influence on the dyeing rate of the two dyes, and the dyeing fastness is good. The experimental procedure involved many compounds, such as 6-Nitrobenzo[d]thiazol-2-amine (cas: 6285-57-0) .
