Related Products of 350-30-1On March 31, 2021, Chen, Jinyi; Wang, Hongxing published an article in Journal of Chemical Thermodynamics. The article was 《Density, viscosity, and saturated vapour pressure of 3-chloro-4-fluoronitrobenzene and 3-chloro-2-fluoronitrobenzene》. The article mentions the following:

D. and viscosity data of pure 3-chloro-4-fluoronitrobenzene and 3-chloro-2-fluoronitrobenzene were obtained in temperature range from 318.15 K to 348.15 K at the local atm. pressure of 99.7 kPa. The value of corresponding saturated vapor pressure of two isomers were determined in the temperature range of 409 K to 517 K. The relationship between temperature and d. can be well correlated by the linear equation. The viscosity data was well described by the Litovitz, Ghatee, VFT, and Andrade equations, and the calculated value by the VFT equation is consistent with the measured data. Both the Antoine and Riedel equations can accurately describe the relationship between saturated vapor pressure and temperature of 3-chloro-4-fluoronitrobenzene and 3-chloro-2-fluoronitrobenzene, which can meet the requirements for chem. design. In addition, the thermal expansion coefficient was determined based on the d. data, and the molar vaporisation enthalpy of two isomers was evaluated using the Clausius-Clapeyron equation. In the experimental materials used by the author, we found 3-Chloro-4-fluoronitrobenzene(cas: 350-30-1Related Products of 350-30-1)

3-Chloro-4-fluoronitrobenzene(cas: 350-30-1) belongs to organochlorine compounds. The wide structural variety and divergent chemical properties of organochlorides lead to a broad range of names, applications, and properties. Organochlorine compounds have wide use in many applications, though some are of profound environmental concern, with TCDD being one of the most notorious.Related Products of 350-30-1

《Discovery and Characterization of 2,5-Substituted Benzoic Acid Dual Inhibitors of the Anti-apoptotic Mcl-1 and Bfl-1 Proteins》 was published in Journal of Medicinal Chemistry in 2020. These research results belong to Kump, Karson J.; Miao, Lei; Mady, Ahmed S. A.; Ansari, Nurul H.; Shrestha, Uttar K.; Yang, Yuting; Pal, Mohan; Liao, Chenzhong; Perdih, Andrej; Abulwerdi, Fardokht A.; Chinnaswamy, Krishnapriya; Meagher, Jennifer L.; Carlson, Jacob M.; Khanna, May; Stuckey, Jeanne A.; Nikolovska-Coleska, Zaneta. Computed Properties of C4H3ClO2S2 The article mentions the following:

Anti-apoptotic Bcl-2 family proteins are overexpressed in a wide spectrum of cancers and have become well validated therapeutic targets. Cancer cells display survival dependence on individual or subsets of anti-apoptotic proteins that could be effectively targeted by multimodal inhibitors. We designed a 2,5-substituted benzoic acid scaffold that displayed equipotent binding to Mcl-1 and Bfl-1. Structure-based design was guided by several solved cocrystal structures with Mcl-1, leading to the development of compound 24, which binds both Mcl-1 and Bfl-1 with Ki values of 100 nM and shows appreciable selectivity over Bcl-2/Bcl-xL. The selective binding profile of 24 was translated to on-target cellular activity in model lymphoma cell lines. These studies lay a foundation for developing more advanced dual Mcl-1/Bfl-1 inhibitors that have potential to provide greater single agent efficacy and broader coverage to combat resistance in several types of cancer than selective Mcl-1 inhibitors alone. After reading the article, we found that the author used Thiophene-2-sulfonyl chloride(cas: 16629-19-9Computed Properties of C4H3ClO2S2)

Thiophene-2-sulfonyl chloride(cas: 16629-19-9) is a member of sulfonyl chlorides.

Four series of mol. hybrids (37 final products) of neo-tanshinlactone, a natural product extracted from Salvia miltiorrhiza Bunge, and known PD-1/PD-L1 interaction inhibitors were prepared as possible chemotherapeutic agents against triple neg. breast cancer. Screening using a homogenous time-resolved fluorescence method resulted in three lead compounds (MZ52 IC50 74 ± 4 nM; MZ58 IC50 134 ± 17 nM; MZ61 IC50 225 ± 19 nM). With less T cell cytotoxicity and effects in activating CD8+ T cells in a T cell proliferation assay and a functionality experiment, MZ58 was selected as the best candidate for animal experiments MZ58 exhibited antitumor effects in a s.c. transplantation tumor model as well as effects in reducing T cell exhaustion. In conclusion, after in vivo and in vitro experiments, we successfully acquired an effective candidate (MZ58) showing antitumor effects with low cytotoxicity toward T cells as well as the ability to activate CD8+ T cells and reduce T cell exhaustion.

Quality Control of Methyl 2-chloro-2-oxoacetateIn 2020 ,《Targeted Covalent Inhibition of Plasmodium FK506 Binding Protein 35》 appeared in ACS Medicinal Chemistry Letters. The author of the article were Atack, Thomas C.; Raymond, Donald D.; Blomquist, Christa A.; Pasaje, Charisse Flerida; McCarren, Patrick R.; Moroco, Jamie; Befekadu, Henock B.; Robinson, Foxy P.; Pal, Debjani; Esherick, Lisl Y.; Ianari, Alessandra; Niles, Jacquin C.; Sellers, William R.. The article conveys some information:

FK506-binding protein 35, FKBP35, has been implicated as an essential malarial enzyme. Rapamycin and FK506 exhibit antiplasmodium activity in cultured parasites. However, due to the highly conserved nature of the binding pockets of FKBPs and the immunosuppressive properties of these drugs, there is a need for compounds that selectively inhibit FKBP35 and lack the undesired side effects. In contrast to human FKBPs, FKBP35 contains a cysteine, C106, adjacent to the rapamycin binding pocket, providing an opportunity to develop targeted covalent inhibitors of Plasmodium FKBP35. Here, we synthesize inhibitors of FKBP35, show that they directly bind FKBP35 in a model cellular setting, selectively covalently modify C106, and exhibit antiplasmodium activity in blood-stage cultured parasites. In the experimental materials used by the author, we found Methyl 2-chloro-2-oxoacetate(cas: 5781-53-3Quality Control of Methyl 2-chloro-2-oxoacetate)
