Mechanically Triggered Small Molecule Release from a Masked Furfuryl Carbonate

Stimuli-responsive polymers that release small molecules under mechanical stress are appealing targets for applications ranging from drug delivery to sensing. Here, we describe a modular mechanophore design platform for molecular release via a mechanically triggered cascade reaction. Mechanochemical activation of a furan-maleimide Diels-Alder adduct reveals a latent furfuryl carbonate that subsequently decomposes under mild conditions to release a covalently bound cargo molecule. The computationally guided design of a reactive secondary furfuryl carbonate enables the decomposition and release to proceed quickly at room temperature after unmasking via mechanical force. This general strategy is demonstrated using ultrasound-induced mechanical activation to release a fluorogenic coumarin payload from a polymer incorporating a chain-centered mechanophore.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 1585-90-6, and how the biochemistry of the body works.Product Details of 1585-90-6

N-heterocyclic carbene-catalyzed annulation of alpha-cyano-1,4-diketones with ynals

In this paper, the first stereoselective annulation reaction between r-cyano-1,4-diketones and ynals, mediated by catalytic amounts of a triazolium salt precatalyst and cocatalytic amounts of a weak carboxylate base, is disclosed. The title transformation proceeds smoothly under mild reaction conditions and generates three contiguous stereogenic centers, one of which is a quaternary acetal carbon. This reaction tolerates a wide variety of electronically distinct substituents on both reaction partners and affords privileged bicyclic scaffolds in 61-90% isolated yields and with up to 20:1 diastereomeric preference.

Two Pairs of Enantiomeric Alkaloid Dimers from Macleaya cordata

Two pairs of enantiomeric alkaloid dimers, (¡À)-macleayins A (1) and B (2), representing a novel dimerization pattern of two different types of alkaloids via a C-C sigma-bond, were isolated from the aerial parts of Macleaya cordata. The enantiomeric separation was achieved by chiral chromatography. Their structures and stereochemistry were determined by the analysis of extensive spectroscopic data, electronic circular dichroism calculation, and single-crystal X-ray diffraction data. (-)-Macleayin A exhibits modest cytotoxic activity against HL-60 cell line with the IC50 value of 3.51 muM.

A NIR facile, cell-compatible fluorescent sensor for glutathione based on Michael addition induced cascade spirolactam opening and its application in hepatocellular carcinoma

A NIR fluorescence probe with long emission wavelength at 746 nm and high quantum yield of 0.36 was designed and synthesized to selectively detect GSH over Hcy and Cys in living systems. 2-(1,3,3-Trimethylindolin-2-ylidene)acetaldehyde was attached to rhodamine by Knoevenagel condensation to shift the emission to near infrared region. Then, ethylenediamine was linked to M2 get an important intermediate M3. Finally, target molecule named RhNM was synthesized through combined N-[4-(carbonyl)phenyl] with M3. RhNM shows excellent discrimination in detecting GSH from Hcy/Cys along with an obvious color change. The fluorescence band at 746 nm is rapidly enhanced 106-fold after adding GSH, and the quantum was calculated at 0.36. Titration experiments of GSH showed good linear relationship of intensity vs. GSG concentration, and the detection limit was calculated at 70 nM. The proposed mechanism for identifying GSH based on Michael addition involves reactions of the carbon-carbon double bond and subsequent spirolactam opening. Meanwhile, the probe RhNM can work in a wide range of pH of 4-10. The probe RhNM was used for endogenous and exogenous imaging in HepG2 cells for glutathione. There was an outstanding intracellular red fluorescence occurring upon the addition of GSH incubated with HepG2 cells. It has been successfully applied for the determination of GSH in diluted serum and for bio-imaging of GSH in living cells with low cell toxicity. All results indicated that the probe can be used as an ultra-sensitive, near-infrared fluorescent chemical sensor for selectively detecting GSH in living cell. It has great potential in imaging of live tissues and even, animal imaging.

Synthesis and biological evaluation of pyrrolinic isosteres of rilmenidine. Discovery of cis-/trans-dicyclopropylmethyl-(4,5-dimethyl-4,5-dihydro-3H-pyrrol-2-yl)- amine (LNP 509), an I1 imidazoline receptor selective ligand with hypotensive activity

To find new compounds selective for purported I1 imidazoline receptors (I1Rs), over I2 imidazoline binding sites (I2BS) and alpha2-adrenoceptors (alpha2ARs), a series of pyrrolinic isosteres of rilmenidine has been prepared and their biological activity at I1Rs, I2BS, and alpha2ARs evaluated. This isosteric replacement provided us with compounds which still bound to I1Rs but not to I2BS nor to alpha2-ARs. A limited structure-affinity relationship was generated around the heterocyclic moiety of these ligands. One compound in this series, LNP 509 (1e) [cis-/trans-dicyclopropylmethyl-(4,5-dimethyl-4,5-dihydro-3H-pyrrol-2-yl) -amine], had no detectable affinity at alpha2ARs yet was capable of lowering blood pressure after central administration. These pyrrolinic analogues constitute a new chemical class of imidazoline related compounds with high selectivity for the I1Rs. They could be used as new tools in the study of I1Rs and in the conception of new centrally acting hypotensive drugs.

Experimental and theoretical studies on the rotational barrier of 1-acyl- and 1-alkoxycarbonyl-2-pyrrolines

The conformational equilibrium as a result of the N-carbonyl bond rotation of several N-acyl- and N-alkoxycarbonyl-2-pyrrolines have been studied. The equilibrium constants and the rotational barriers were determined by theoretical methods (AM1, PM3, HF/3-21G(*) and HF/6-31G*) and, experimentally, by dynamic NMR (coalescence temperature). The measured rotational barriers for enecarbamates were found to be ca. 16 kcal mol-1 in C6D6 or C6D5NO2, whereas slightly higher values were found for enamides in C6D5NO2. Contrary to enamides, the rotational barriers for enecarbamates were not affected by changes in the polarity of the solvent employed.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Optimization of the N-lost drugs melphalan and bendamustine: Synthesis and cytotoxicity of a new set of dendrimer-drug conjugates as tumor therapeutic agents

Bendamustine and melphalan are very promising alkylating drugs with applicability in the treatment of various tumoral diseases, e.g., chronic lymphocytic leukemia (CLL) or breast cancer. However, numerous adverse effects limited their use. Therefore, 1,3,5-tris(3-aminopropyl)benzene (G0) and its G1 analogue 3,5-bis(3-aminopropyl)-N-(3-{3,5-bis[3-{3,5-bis(3-aminopropyl) benzoylamino}propyl]phenyl}propyl)benzamide were selected to design cytostatic drug-dendrimer conjugates to achieve tumor cell accumulation by endocytosis as already demonstrated for platinum complexes. The dendrimers act as carriers and an N-(2-hydroxyethyl)maleimide spacer between drug and carrier should guarantee a selective release of the cytostatics in the tumor cells. The resulting cytotoxicity was determined in vitro using the human MCF-7 and MDA-MB-231 breast cancer cell lines. It was demonstrated that melphalan caused cytotoxic effects depending on its free amino group (Boc protection strongly decreased the activity) but independent of a derivation of the carboxylic group (dendrimers and spacer binding). Esterification of bendamustine with the N-(2-hydroxyethyl)maleimide spacer strongly increased the hydrolytic stability of the N-lost moiety, so antiproliferative effects were yet observed in vitro.
