Inspired by marine mussel adhesive proteins, polymers with catechol side groups have been extensively explored in industrial and academic research. Here, Pluronic L-31 alcoholate ions were used as the initiator to prepare a series of polypeptide–Pluronic–polypeptide triblock copolymers via ring-opening polymerization l-DOPA-N-carboxyanhydride (DOPA-NCA), l-arginine-NCA (Arg-NCA), l-cysteine-NCA (Cys-NCA), ε-N-acryloyl lysine-NCA (Ac-Lys-NCA). These demonstrated good biodegradability,...

[reaction: see text] Under very mild conditions, functionalized 2-(sulfonylimino)-4-(alkylimino)azetidine derivatives were prepared in good to excellent yields via a copper-catalyzed multicomponent reaction of readily available terminal alkynes, sulfonyl azides, and carbodiimides without the assistance base. The mechanism may be through [2 + 2] cycloaddition.

The introduction of new treatments for esophageal cancer including surgery, chemotherapy, radiotherapy, or a combination these modalities has not only improved patient survival, but may also increase the risk second primary cancers. available evidence is conflicting with most estimates based on sparse numbers. Here we estimated standardized incidence ratios (SIRs) among 24,557 survivors (at least 2 months) in Surveillance, Epidemiology, and End Results (SEER) Program between 1973 2007, who...

Ruthenium catalyst TpRuPPh3(CH3CN)2Cl is found to effect the cyclization of epoxyalkynes furans in presence Et3N. The reactions worked well for various with suitable oxygen and nitrogen functionalities low loading catalyst. It failed disubstituted epoxyalkynes. mechanism was elucidated by a deuterium labeling experiment that suggested involved ruthenium−vinylidenium intermediate.

Abstract Functionalized propiolamidine derivatives were prepared in good to excellent yields under very mild conditions via a copper‐catalyzed multicomponent reaction (MCR) of readily available terminal alkynes, acid chlorides and carbodiimides with the assistance triethylamine. The mechanism this MCR is postulated.

Abstract A basic ionic liquid, 1‐butyl‐3‐methyl imidazolium hydroxide ([bmim]OH), efficiently promotes a one‐pot, three‐component condensation of aromatic aldehydes, malononitrile or ethyl cyanoacetate, and 2‐hydroxy‐1,4‐naphthoquinone to produce 4‐aryl‐5,10‐dihydro‐4 H ‐benzo[ g ]chromene‐5,10‐dione derivatives in high yields at room temperature. This reaction does not involve any hazardous organic solvent toxic catalyst. The liquid is recovered recycled for subsequent reactions. Moreover,...

Transcatheter arterial embolization (TAE) has been widely applied in treatments of unresectable or hypervascular tumors, but the procedure TAE is complicated possibly brings inherent risks. Here, inspired by pH-responsive drug delivery systems, a new method noninvasive and target therapy intravenous injection was developed. This based on type acidic microenvironment-responsive hyperbranched poly(amino acid) (HPTTG) to avoid using catheterization real-time image guidance angiography,...

Skeletal muscle is a major organ in animals, which constitutes over 40% of livestock body weight, and plays critical role metabolism homeostasis an organism. Autophagy apoptosis are two processes to determine cell fate. Recently, the importance autophagy myogenesis has been identified; however, their crosstalk not well defined. In this study, we aimed explore relationship between during myogenic differentiation. The results showed that level was consistent with increased activated autophagy,...
