The development of molecular theranostic prodrugs for in vivo cancer diagnosis and targeted chemotherapy is urgently required. Enzyme-activated prodrugs display superior selectivity as a result of cancer-specific enzymes which serve as cancer biomarkers. Herein, an aminopeptidase N (APN)-activated theranostic prodrug Nile blue-C-6-amide-p-fluorophenylalanyl-l-melphalanyl (NBFMel) is reported for fluorescence cancer diagnosis and local tumor treatment. NBFMel demonstrates negligible cytotoxicity and very weak fluorescence due to the photoinduced electron transfer (PET) between melphalan and Nile blue fluorophore. After activation caused by APN, the prodrug releases free melphalan that inhibits tumor cell growth. Simultaneously, the reaction blocks the PET process and switches on the fluorescence, which can be used for cancer diagnosis. NBFMel is successfully utilized to report the presence of tumor and for in situ tracking of drug release in tumor-bearing mouse models. Moreover, NBFMel demonstrates efficient tumor inhibition when intravenously injected into mice. Therefore, the APN-activated theranostic prodrug provides a new platform for in vivo cancer diagnosis and targeted anticancer chemotherapy.

The aims of this study are to isolate and characterize acid soluble collagen (ASC) and pepsin soluble collagen (PSC) extracted from silver catfish (Pangasius sp.) skin. Isolated ASC and PSC collagen were characterized in terms of chemical composition (moisture, protein, fat and ash content), protein concentration, functional group, solubility, and morphological properties as compared to commercial collagen. Yields of ASC and PSC were 4.27% and 2.27%, respectively. The chemical compositions of raw skin were 34.64%, 2.81%, 3.68%, and 0.31%, while the chemical compositions of ASC and PSC were 94.21%, 3.48%, 0.81%, 59.15%, and 88.25%, 3.46%, 0.92%, and 29.24%, for moisture, protein, fat, and ash, respectively. ASC and PSC had protein concentrations of 2.27 mg/mL and 2.70 mg/mL, respectively. Functional group analysis revealed that both isolated collagens exhibited Amide A, II and III as a fingerprint for collagen structure. The highest solubility was found at pH 4 for ASC, pH 1 for PSC, and pH 5 for commercial collagen. The morphology of the isolated collagens was porous and they contained fibril. In conclusion, the characteristics of the isolated ASC and PSC from silver catfish (Pangasius sp.) skin indicate that value-added collagen can be produced from the alternative source of freshwater fish.

An efficient and clean protocol was developed for rapid production of primary aromatic amides by aminocarbonylation with NH4HCO3. Without addition of auxiliary base, the use of solid and cheap NH4HCO3 dually as ammonia surrogate and base not only promoted aminocarbonylation over subsequent dehydration and hydrolysis of amides owing to its weak basicity, and it also made the reaction manipulation clean and simplified without the presence of stinky NH3 or organic amines. The Xantphos ligand with relatively intensive -acceptor character ((1)J(31P-77Se)=758Hz) and wide natural bite angle (beta(n)=111 degrees) was found to be indispensable for the high efficiency of this reaction.

Synthesis of new biobased linear poly(ester amide)s

In the present work, we investigated the synthesis of new biobased linear aliphatic PEAs with a controlled regicity, in a two steps procedure. First, dioldiamide derivatives were successfully synthesized, then polycondensation reaction using the usual alcohol plus acid reaction was performed. NMR analyses demonstrate that dioldiamide can be synthesized in one step from diacid and ethanolamine condensation with high conversion. A new library of polymers was then synthesized, and characterized. Overall, the reactivity of amine or alcohol or acid functions is investigated by in-depth H-1 and C-13 NMR versus HSQC NMR analysis. These results can be used to follow the complex evolution of monoesterification or diesterification reactions, monoamidation or diamidation reactions when dicarboxylic acids versus alcohol or amine are reacted. Thermal degradation was examined, and a good stability of all the polymers was evidenced. The thermal properties of the polymers were also analyzed, and high melting temperatures were measured, thanks to the control of the regicity. Comparing the melting and crystallization temperature revealed a fast rate of crystallization, an important feature for polymer melt processing. The solubility behavior of these polymers was found to be close to the one of polyamides, suggesting the use of this new polymers library to replace polyamides in applications where biodegradability of the materials is required.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 33208-99-0 is helpful to your research. Product Details of 33208-99-0.

Palladium-Catalyzed Site-Selective [3+2] Annulation via Benzylic and meta C-H Bond Activation

The palladium-catalyzed [3+2] annulation of aromatic amides with maleimides via the activation of ortho benzylic C-H and meta C-H bonds is reported. Carboxamide and anilide type substrates that contain a 2-methylthiophenyl group both participate in this [3+2] annulation, indicating that the presence of a 2-methylthiophenyl directing group is a key for the success of the reaction. The first C-H bond activation at the benzylic C-H bond is followed by a second C-H bond activation at the meta C-H bond to give five-membered cyclic products. The cleavage of these C-H bonds is irreversible.

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. you can also check out more blogs about 33208-99-0. Recommanded Product: 33208-99-0.

Accelerating the Shuttling in Hydrogen-Bonded Rotaxanes: Active Role of the Axle and the End Station

The relation between the chemical structure and the mechanical behavior of molecular machines is of paramount importance for a rational design of superior nanomachines. Here, we report on a mechanistic study of a nanometer scale translational movement in two bistable rotaxanes. Both rotaxanes consist of a tetra-amide macrocycle interlocked onto a polyether axle. The macrocycle can shuttle between an initial succinamide station and a 3,6-dihydroxy- or 3,6-di-tert-butyl-1,8-naphthalimide end stations. Translocation of the macrocycle is controlled by a hydrogen-bonding equilibrium between the stations. The equilibrium can be perturbed photochemically by either intermolecular proton or electron transfer depending on the system. To the best of our knowledge, utilization of proton transfer from a conventional photoacid for the operation of a molecular machine is demonstrated for the first time. The shuttling dynamics are monitored by means of UV-vis and IR transient absorption spectroscopies. The polyether axle accelerates the shuttling by similar to 70% compared to a structurally similar rotaxane with an all-alkane thread of the same length. The acceleration is attributed to a decrease in activation energy due to an early transition state where the macrocycle partially hydrogen bonds to the ether group of the axle. The dihydroxyrotaxane exhibits the fastest shuttling speed over a nanometer distance (tau(shuttling) approximate to 30 ns) reported to date. The shuttling in this case is proposed to take place via a so-called harpooning mechanism where the transition state involves a folded conformation due to the hydrogen-bonding interactions with the hydroxyl groups of the end station.

Analysis of tuberculosis disease through Raman spectroscopy and machine learning

We present the effectiveness of Raman spectroscopy (RS) in combination with machine learning for screening and analysis of blood sera collected from tuberculosis patients. Blood samples of 60 patients have confirmed active pulmonary tuberculosis and 14 samples of healthy age matched control were used in the current study. Spectra from entire sera samples were acquired using 785 nm laser Raman system. Support Vector Machine (SVM) together with Principal Component Analysis (PCA) has been used for highlighting variations spectral intensities between healthy and pathological samples. SVM model using Gaussian radial basis is able to discriminate between healthy and diseased patients based on the differences in the concentration of essential biomolecules such as lactate, beta-carotene, and amide-I. Diagnostic accuracy of 92%, with precision, specificity and sensitivity of 95%, 98% and 81%, respectively, were achieved considering PC3 and PC4. Automatic analysis of the variations in the concentration of these molecules together with chemometrics can effectively be utilized for an early screening of tuberculosis through minimum invasion.
