BODIPY-based ratiometric fluoroionophores with bidirectional spectral shifts for the selective recognition of heavy metal ions

Two novel asymmetric BODIPY fluoroionophores with dipicolylamine (BDP-DPA, dipicolylamine: bis(pyridylmethyl)) and terpyridine (BDP-TPY) are described. These fluoroionophores display opposite wavelength responses on complexation with heavy metal ions. Furthermore, the fluorescence spectra vary depending on the ionic species. In particular, BDP-DPA shows a high affinity toward Cr3+ and upon complexation, the fluorescence spectrum blue-shifts from 591 to 566 nm. In contrast, BDP-TPY preferentially binds to Zn2+ and the fluorescence spectra red-shifts from 539 to 567 nm. BDP-TPY is the first example of asymmetric BODIPY with a pyridyl receptor at the 3 position showing redshifted fluorescence by complexation with metal ions. The concentration of each metal ion was successfully determined by ratiometric measurement. The wavelength-responses characteristics of these fluoroionophores could be very useful in the development of novel ratiometric fluoroionophores for metal ions.

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.

Synthesis of the tricyclic core of the marine alkaloid lepadiformine

A stereoselective synthesis of the tricyclic core in racemic form of the marine alkaloid Lepadiformine is described from 4-methoxy-3-pyrrolin-2-one (methyl tetramate). Key steps involve 5,5-dialkylation of the tetramate, metathesis closure to an A/C 1-azaspirocycle and stereoselective hydrogenation for the trans A/B 1-azadecalin system.

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. Recommanded Product: N-Boc-2-pyrroline, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 73286-71-2, in my other articles.

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.

Batch versus flow photochemistry: A revealing comparison of yield and productivity

The use of flow photochemistry and its apparent superiority over batch has been reported by a number of groups in recent years. To rigorously determine whether flow does indeed have an advantage over batch, a broad range of synthetic photochemical transformations were optimized in both reactor modes and their yields and productivities compared. Surprisingly, yields were essentially identical in all comparative cases. Even more revealing was the observation that the productivity of flow reactors varied very little to that of their batch counterparts when the key reaction parameters were matched. Those with a single layer of fluorinated ethylene propylene (FEP) had an average productivity 20% lower than that of batch, whereas three-layer reactors were 20% more productive. Finally, the utility of flow chemistry was demonstrated in the scale-up of the ringopening reaction of a potentially explosive [1.1.1] propellane with butane-2,3-dione.
