In 2022,Li, Xipeng; Zeng, Qin; Zhang, Ruijing; Li, Jiajun; Xing, Da; Zhang, Tao published an article in Chemical Engineering Journal (Amsterdam, Netherlands). The title of the article was 《Mitochondria-specific gadolinium (III) porphyrinate as efficient ROS generator for MRI visualization and sonodynamic-immunotherapy of deep localized tumors》.Related Products of 26153-38-8 The author mentioned the following in the article:

Conventional sonodynamic therapy (SDT) is still limited in conquering localized tumors owing to its low reactive oxygen species (ROS)-based therapeutic effect and undesirably inhibiting effect of immunosuppressive tumor microenvironment (ITM). In this study, we reasonably designed a new sonosensitizer, gadolinium (III) porphyrinate (GdPorP), which could efficiently produce ROS upon ultrasound irradiation and specifically accumulate in mitochondria. The GdPorP-based mitochondria-specific sonodamage could induce high-efficiency cell apoptosis and cascade to producing large-scale immunogenic cell death. After GdPorP systematically delivered together with the indoleamine 2,3-dioxygenase (IDO) inhibitor by a pH-sensitive nanomedicine, the localized liver tumor was specifically mapped by the “”switching-on”” MRI. And the nanomedicine could not only efficiently suppress the progression of primary liver tumors but also simultaneously boost the systematic antitumor immune effect via the inhibition of ITM. The GdPorP-approved sonodynamic-immunotherapy (SDIT) has thereby been established as a new paradigm for upgrading the efficacy of cancer SDT. In the experiment, the researchers used 3,5-Dihydroxybenzaldehyde(cas: 26153-38-8Related Products of 26153-38-8)

Recommanded Product: 156-87-6In 2021 ,《Prediction of Surface Tension of Various Aqueous Amine Solutions Using the UNIFAC Model and Artificial Neural Networks》 was published in Industrial & Engineering Chemistry Research. The article was written by Mousavi, Nayereh Sadat; Vaferi, Behzad; Romero-Martinez, Ascencion. The article contains the following contents:

In the first stage of this work, a thermodn. approach based on the equality of chem. potentials together with the original UNIFAC activity coefficient model was used to predict the surface tension of 11 different aqueous amine solutions over the entire concentration range at the temperature range of 293.15-348.15 K. The considered aqueous amine solutions include one of the following amines: monoethanolamine, diethanolamine, di-isopropanolamine, Me diethanolamine, 1-amino-2-propanol, triethanolamine, 3-dimethylamino-1-propylamine, 3-amino-1-propanol, dimethylethanolamine, 2-methylamino ethanol, and 2-ethylamino ethanol. The effect of temperature, amine concentration in the aqueous solution, and hydrophobic groups such as -CH2 and -CH3 on the surface tension of primary, secondary, and tertiary amines was investigated. In the second stage, the multilayer perceptron neural network model is designed to predict the surface tension of the aqueous solutions from two different classes of independent variables. The UNIFAC and two developed multilayer perceptron models were used to predict 650 surface tension values, which were in turn used to compare to exptl. data points with the average absolute relative deviations of 6.79, 1.17, and 1.12%, resp. In the experiment, the researchers used many compounds, for example, 3-Aminopropan-1-ol(cas: 156-87-6Recommanded Product: 156-87-6)

3-Aminopropan-1-ol(cas: 156-87-6) belongs to anime. Halogenation, in which one or more hydrogen atoms of an amine is replaced by a halogen atom, occurs with chlorine, bromine, and iodine, as well as with some other reagents, notably hypochlorous acid (HClO). With primary amines the reaction proceeds in two stages, producing N-chloro- and N,N-dichloro-amines, RNHCl and RNCl2, respectively. With tertiary amines, an alkyl group may be displaced by a halogen.Recommanded Product: 156-87-6

In 2020,International Journal of Molecular Sciences included an article by Imperatore, Concetta; Valadan, Mohammadhassan; Tartaglione, Luciana; Persico, Marco; Ramunno, Anna; Menna, Marialuisa; Casertano, Marcello; Dell’Aversano, Carmela; Singh, Manjot; d’Aulisio Garigliota, Maria Luisa; Bajardi, Francesco; Morelli, Elena; Fattorusso, Caterina; Altucci, Carlo; Varra, Michela. Category: alcohols-buliding-blocks. The article was titled 《Exploring the photodynamic properties of two antiproliferative benzodiazopyrrole derivatives》. The information in the text is summarized as follows:

The identification of mols. whose biol. activity can be properly modulated by light is a promising therapeutic approach aimed to improve drug selectivity and efficacy on the mol. target and to limit the side effects compared to traditional drugs. Recently, two photo-switchable diastereomeric benzodiazopyrrole derivatives 1RR and 1RS have been reported as microtubules targeting agents (MTAs) on human colorectal carcinoma p53 null cell line (HCT 116 p53-/-). Their IC50 was enhanced upon Light Emitting Diode (LED) irradiation at 435 nm and was related to their cis form. Here we have investigated the photo-responsive behavior of the acid derivatives of 1RR and 1RS, namely, d1RR and d1RS, in phosphate buffer solutions at different pH. The comparison of the UV spectra, acquired before and after LED irradiation, indicated that the trans→cis conversion of d1RR and d1RS is affected by the degree of ionization. The apparent rate constants were calculated from the kinetic data by means of fast UV spectroscopy and the conformers of the putative ionic species present in solution (pH range: 5.7-8.0) were modelled. Taken together, our exptl. and theor. results suggest that the photo-conversions of transd1RR/d1RS into the corresponding cis forms and the thermal decay of cisd1RR/d1RS are dependent on the presence of diazonium form of d1RR/d1RS. Finally, a photo-reaction was detected only for d1RR after prolonged LED irradiation in acidic medium, and the resulting product was characterized by means of Liquid Chromatog. coupled to High resolution Mass Spectrometry (LC-HRMS) and NMR spectroscopy.(R)-Oxiran-2-ylmethanol(cas: 57044-25-4Category: alcohols-buliding-blocks) was used in this study.

Aim of present work was to develop and validate a simple, precise and accurate uv-vis spectrophotometric method for the simultaneous estimation of gemifloxacin mesylate (GEMI) and ambroxol HCl (AMB) in their combined tablet dosage form. The method is based on first-order derivative spectroscopy. For determination of sampling wavelengths, each of GEMI and AMB were scanned in the wavelength range of 200-400 nm in the spectrum mode and sampling wavelengths were selected at 360 nm (zero crossing of GEMI) where AMB showed considerable absorbance and at 221.6 nm (zero crossing of AMB) where GEMI showed considerable absorbance. The linearity was obtained in the concentration range of 32-192μg/mL for GEMI and 7.5-45μg/mL for AMB. The correlation coefficients were found to be 0.9987 and 0.9992 for GEMI and AMB, resp. The method was validated as per ICH guidelines. Mean recoveries were found satisfactory. All the data of validation study was found to be satisfactorily. The proposed method can be applied for simultaneous estimation of both the drugs.
