In 2019,Chemical Communications (Cambridge, United Kingdom) included an article by Tanini, Damiano; Lupori, Beatrice; Malevolti, Gianni; Ambrosi, Moira; Nostro, Pierandrea Lo; Capperucci, Antonella. Safety of Methyl 3-bromopropanoate. The article was titled 《Direct biocatalysed synthesis of first sulfur-, selenium- and tellurium- containing L-ascorbyl hybrid derivatives with radical trapping and GPx-like properties》. The information in the text is summarized as follows:

6-O-L-Ascorbyl selenoesters, thioesters and telluroesters, e.g., I, II, and III, resp., can be efficiently and directly prepared from L-ascorbic acid and suitable functionalized chalcogenoesters through lipase-catalyzed transesterification reactions. Novel synthesized L-ascorbyl derivatives exhibited remarkable chain breaking and glutathione peroxidase-like activities. The experimental part of the paper was very detailed, including the reaction process of Methyl 3-bromopropanoate(cas: 3395-91-3Safety of Methyl 3-bromopropanoate)

Methyl 3-bromopropanoate(cas: 3395-91-3) belongs to bromides. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. Bromine is more electronegative than carbon (2.9 vs 2.5). Consequently, the carbon in a carbon–bromine bond is electrophilic, i.e. alkyl bromides are alkylating agents.Safety of Methyl 3-bromopropanoate

Recommanded Product: Methyl 3-bromopropanoateIn 2019 ,《Rational Design of a Multifunctional Molecular Dye with Single Dose and Laser for Efficiency NIR-II Fluorescence/Photoacoustic Imaging Guided Photothermal Therapy》 appeared in Analytical Chemistry (Washington, DC, United States). The author of the article were Zhang, Ruiping; Wang, Zhenjun; Xu, Liying; Xu, Yuling; Lin, Yi; Zhang, Ying; Sun, Yao; Yang, Guangfu. The article conveys some information:

Multifunctional probes integrating accurate multi-diagnosis and efficient therapy hold great prospect in biomedical research. However, the sophisticated construction and difficulties in matching the ratios of doses and laser triggers of probes for each modality imaging and therapy are still hindered the extensive practice of multifunctional probes in biomedicine. We herein rational designed an organic dye SY1080 with intrinsic multifunction by both introducing 3,4-ethylenedioxy thiophene (EDOT) and the selenium containing acceptor unit into the backbone to balance the fluorescence brightness and emission wavelength. Under single dose and 808 nm laser irradiation conditions, SY1080 not only carried out NIR-II fluorescence/Photoacoustic imaging of real-time and noninvasive tumor delineation with excellent contrast, but also effectively ablated tumors with laser irradiation to perform PTT under the guidance of dual-modal imaging. These exciting results highlighted SY1080 as a multifunctional and universal phototheranostic platform for potential applications. In the part of experimental materials, we found many familiar compounds, such as Methyl 3-bromopropanoate(cas: 3395-91-3Recommanded Product: Methyl 3-bromopropanoate)

Methyl 3-bromopropanoate(cas: 3395-91-3) belongs to bromides. One prominent application of synthetic organobromine compounds is the use of polybrominated diphenyl ethers as fire-retardants, and in fact fire-retardant manufacture is currently the major industrial use of the element bromine.Recommanded Product: Methyl 3-bromopropanoate

Recommanded Product: 3395-91-3In 2016 ,《Novel 2,4-thiazolidinedione analogues as cytotoxic agents: synthesis and biological screening》 was published in International Journal of Pharmaceutical Research and Bio-Science. The article was written by Shah, Dhaval G.; Patel, Laxman J.. The article contains the following contents:

Novel thiazolidinedione derivatives I (R1 = H, CH2CO2H, CH2CO2Et, etc.; R2 = benzoyl, 2,3-dichlorobenzoyl, 2,4-dichlorobenzoyl, etc.) were synthesized via reaction of N-benzoyl substituted aryl alkyl halide with N-substituted 2,4-thiazolidinedione derivatives and screened for their in vitro cytotoxic activity by MTT assay. The cell lines used were MCF 7 (Breast cancer cell), HELA (Cervical cancer cell line), HEK (Normal epidermal kidney cell line) HEP (Laryngeal cancer cell line) MDA MB 468 (Breast cancer cell line). Screening results showed moderate to good cytotoxic activity for all the compounds Compound I (R1 = CH2CO2H; R2 = 4-chlorobenzoyl) (IC50 = 3.63 μM, HEP, IC50 = 1.07 μM, HEK) and compound I (R1 = CH2CO2H; R2 = 2,3-dichlorobenzoyl) (IC50 = 1.09 μM, HELA, IC50 = 1.989 μM, M468, IC50 = 2.5 μM, MCF7) were found to be most active compared to standard methotrexate (IC50 = 0.22 μM HEP, IC50 = 0.072 μM HEK, IC50 = 0.102 μM HELA, IC50 = 0.152 μM M468, IC50 = 0.100 μM MCF7). Structure activity relationship of synthesized analogs suggested that the attachment of electron withdrawing groups like chloro at R2 position and acetyl group at R1 gave better cytotoxic activity. Activity by hydrogen and acetyl substitution at R1 position linked with N-substituted 2,4-thiazolidinedione scaffold gave better activity in the order of H > CH2COOH. These findings may impart new direction to medicinal chemists and biochemists for further investigations of 2,4-thiazolidinedione containing cytotoxic agents. In the experiment, the researchers used many compounds, for example, Methyl 3-bromopropanoate(cas: 3395-91-3Recommanded Product: 3395-91-3)

SDS of cas: 3395-91-3In 2019 ,《Quantitative structure-activity and quantitative structure-property relationship approaches as alternative skin sensitization risk assessment methods》 was published in Journal of Toxicology and Environmental Health, Part A: Current Issues. The article was written by Kim, Ji Yun; Kim, Min Kook; Kim, Kyu-Bong; Kim, Hyung Sik; Lee, Byung-Mu. The article contains the following contents:

This study aimed to predict skin sensitization potency of selected chems. by quant. analyzing their physicochem. properties by employing quant. structure-activity relationship (QSAR) and quant. structure-property relationship (QSPR) approaches as alternative risk assessment methods to animal testing. Correlations between effective concentration for a stimulation index of 3 (EC3) (%), the amount of a chem. required to elicit a threefold increase in lymph node cell proliferative activity (stimulation index, ≥3), were calculated using local lymph node assay (LLNA) and physicochem. properties of 212 skin sensitizers and 38 non-sensitizers were investigated. The correlation coefficients between m.p. (MP) and EC3 and between surface tension (ST) and EC3 were 0.65 and 0.69, resp. Thus, correlation coefficients between EC3 and MP, ST, and MP + ST reliably predicted the skin sensitization potential of the chems. with sensitivities of 72% (126/175), 70% (122/174), and 73% (116/158); specificities of 77% (27/35), 69% (22/32), and 81% (26/32); and accuracies of 73% (153/210), 70% (144/206), and 75% (142/190), resp. Our findings suggest that the EC3 value may be more accurately predicted using the ST values of chems. as opposed to MP values. Thus, information on MP and ST parameters of chems. might be useful for predicting the EC3 values as not only an alternative approach to animal testing, but as a risk assessment method for skin sensitization.

Discrete Pt(II) metallacycles have potential applications in biomedicine. Herein, we engineered a dual-modal imaging and chemo-photothermal therapeutic nano-agent 1 that incorporates discrete Pt(II) metallacycle 2 and fluorescent dye 3 (emission wavelength in the second near-IR channel [NIR-II]) into multifunctional melanin dots with photoacoustic signal and photothermal features. Nano-agent 1 has a good solubility, biocompatibility, and stability in vivo. Both photoacoustic imaging and NIR-II imaging in vivo confirmed that 1 can effectively accumulate at tumor sites with good signal-to-background ratio and favorable distribution. Guided by precise dual-modal imaging, nano-agent 1 exhibits a superior antitumor performance and less severe side effects compared with a single treatment because of the high efficiency of the chemo-photothermal synergistic therapy. This study shows that nano-agent 1 provides a promising multifunctional theranostic platform for potential applications in biomedicine.
