All-active antitumor micelles via triggered lipid peroxidation

Traditional antitumor nanomedicines have been suffering from the poor tumor targeting (ca. 1%) by the enhanced permeability and retention (EPR) effect, and the low drug loading (<5%). It was postulated that engineering all-active nanoplatform could increase the therapeutic efficacy to enable the nanocarrier function as both vehicle and active ingredient. To achieve this, a photosensitizer, Ce6 was encapsulated within polymeric micelles with unsaturated fatty acids as the building blocks. Upon light irradiation, the singlet oxygen produced by Ce6 induced lipid peroxidation, resulting in the generation of both active free radicals and aldehydes. These supplementary radicals could exert cytotoxic effect for direct killing tumor cells. The aldehyde end-products induced significant cell cycle arrest at G2 phase in 4T1 cells. The peroxidation process also facilitated the on-demand disassembly of micelles and rapid release of Ce6 to maximize the therapeutic effect of singlet oxygen. These all-active micelles showed a significantly enhanced cytotoxicity with the half maximal inhibitory concentration (IC50) of 0.6 ± 0.2 mug/mL in contrast to the control micelles at 3.4 ± 0.5 mug/mL. The improved antitumor efficacy of the all-active micelles was also demonstrated in the 4T1 tumor-bearing mice in vivo. The current work provides a facile approach to enhance the antitumor efficacy of PDT nanomedicine using the biocompatible fatty acids, which can be applied to various antitumor drugs and unsaturated lipids. 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.Formula: C15H18N2O5, you can also check out more blogs about1676-86-4

Biocatalysis as useful tool in asymmetric synthesis: An assessment of recently granted patents(2014-2019)

The broad interdisciplinary nature of biocatalysis fosters innovation, as different technical fields are interconnected and synergized. A way to depict that innovation is by conducting a survey on patent activities. This paper analyses the intellectual property activities of the last five years (2014-2019) with a specific focus on biocatalysis applied to asymmetric synthesis. Furthermore, to reflect the inventive and innovative steps, only patents that were granted during that period are considered. Patent searches using several keywords (e.g., enzyme names) have been conducted by using several patent engine servers (e.g., Espacenet, SciFinder, Google Patents), with focus on granted patents during the period 2014-2019. Around 200 granted patents have been identified, covering all enzyme types. The inventive pattern focuses on the protection of novel protein sequences, as well as on new substrates. In some other cases, combined processes, multi-step enzymatic reactions, as well as process conditions are the innovative basis. Both industries and academic groups are active in patenting. As a conclusion of this survey, we can assert that biocatalysis is increasingly recognized as a useful tool for asymmetric synthesis and being considered as an innovative option to build IP and protect synthetic routes.

Synthesis of unprecedented steroidal Spiro heterocycles as potential antiproliferative drugs

Herein we report the straightforward preparation of novel conformationally-restricted steroids from trans-androsterone and estrone, decorated with spiranic oxazolidin-2-one or 2-aminooxazoline motifs at C-17 as potential antiproliferative agents. Such unprecedented pharmacophores were accessed using an aminomethylalcohol derivative at C-17 as the key intermediate; reaction of such functionality with triphosgene, or conversion into N-substituted thioureas, followed by an intramolecular cyclodesulfurization reaction promoted by yellow HgO, furnished such spirocycles in excellent yields. Title compounds were tested in vitro against a panel of six human tumor cell lines, named A549 (non small cell lung), HBL-100 (breast), HeLa (cervix), SW1573 (non-small cell lung), T-47D (breast) and WiDr (colon), and the results were compared with steroidal chemotherapeutic agents (abiraterone and galeterone); the A-ring of the steroidal backbone, the nature of the heterocycle and the N-substituents proved to be essential motifs for establishing structure-activity relationships concerning not only the potency but also the selectivity against tumor cell lines. Estrone derivatives, particularly those bearing a spiranic 2-aminooxazoline scaffold were found to be the most active compounds, with Gl(50) values ranging from the low micromolar to the submicromolar level (0.34-1.5 mu M). Noteworthy, the lead compounds showed a remarkable increase in activity against the resistant cancer cell lines (T-47D and WiDr) compared to the anticancer reference drugs (up to 120-fold).

Fluorescent triazolyl spirooxazolidines: Synthesis and NMR stereochemical studies

Carbon-heteoratom chemistry is a method of choice for rapid construction of complex molecules. In the recent decade, its various applications flourished thanks to the click chemistry approach. Herein, we use a combination of C-X bond formation reactions to complete the synthesis of 1,2,3-triazolyl spirooxazolidines, bearing the fluorenylmethoxycarbonyl (fmoc) substituent. Thanks to the application of 2D-NMR spectroscopic methods and a multilevel computational approach, including a medicinal chemistry – inspired conformational search, PM7 semiempirical and DFT-based geometry optimization finalized with DFT-GIAO NMR shielding constant calculation, we were able to investigate the conformational space and assign cis/trans configuration in complex NMR spectra. For the obtained fmoc derivatives we recorded UV-VIS absorption and emission spectra. The obtained compounds contain pharmacophoric groups characteristic for endocannabinoid system modulators- CB1 receptor ligands or FAAH inhibitors. (C) 2019 Elsevier B.V. All rights reserved.

Convenient Synthesis of Pyrimidine acyclo-2,2 ‘-anhydronucleosides and their Exploitation Toward Selected N-nucleophiles

A new method of the synthesis of 2-(hydroxymethyl-2H-oxazolo[3,2-a]pyrimidin-7(3H)-ones, commonly known as pyrimidine acyclo-2,2′-anhydronucleosides, was developed. Under the Mitsunobu reaction conditions, 5-substituted 1-(3′-alkoxy-2′-hydroxypropyl)uracil derivatives underwent an intramolecular cyclization to the corresponding 2-alkoxymethyl-2,3-dihydro-7H-oxazolo[3,2-a]pyrimidin-7-ones. The various synthetic methods have been demonstrated in the reactions with several N-nucleophiles. Importantly from the mechanistic point of view, in the case of 6-bromo-2-(hydroxymethyl)-2H-oxazolo[3,2-a]pyrimidin-7(3H)-one treated with chiral isocyanate the inversion of configuration at the C-4’ carbon atom accompanied by the oxazolidine ring opening was observed.

Synthesis and structural characterization of bis[(4S,5R)-4-methoxycarbonyl-5-methyl-1,3-oxazolidine]copper(II) dichloride and bis[(4S,5R)-4-methoxycar-bonyl-5-methyl-2-oxazoline]-[(4S,5R)-4-methoxycarbonyl-5-methyl-1,3-oxazolidine]ruthenium(III) trichloride

In the reaction of N,N’-methylenebis[(4S,5R)-4-methoxycarbonyl-5-methyloxazolidine] (1) with CuCl2 or RuCl3 in alcoholic solvents novel complexes, bis[(4S,5R)-4-methoxycarbonyl-5-methyl-1,3-oxazolidine]copper(II) dichloride (2) and bis[(4S, 5R)-4-methoxycarbonyl-5-methyl-2-oxazoline]-(4S,5R)-4-methoxycarbonyl-5-methyl-1,3-oxazolidineruthenium(III) trichloride (3), respectively, were isolated and fully characterized by X-ray crystallography. In these reactions, which occurred under mild conditions, ligand 1 was cleaved at the bridging aminal position and degraded to (4S, 5R)-4-methoxycarbonyl-5-methyl-1,3-oxazolidine 5. The trigonal bipyramidal Cu complex 3 contains two such oxazolidine ligands coordinated in different ways. One is bonded in a monodentate fashion via the nitrogen atom of the five-membered ring, the other binds as a bidentate ligand, additionally using the carbonyl oxygen of the ester group. In the octahedral Ru complex 4 there are one oxazolidine ligand 5 and two oxazoline ligands 6. Thus, in the synthesis of 4 the carbon atom between oxygen and nitrogen in the oxazolidine ring was partly oxidized from the half-aminal status to the carboxamide status. (C) 2012 Elsevier B. V.
