Synthesis of an advanced intermediate of alfa-alloenduracididine from allylglycine

open access: yesOrbital: The Electronic Journal of Chemistry, 2012
α-Alloenduracididine, 3-(2-amino-4,5-dihydro-1Himidazole-4-yl)-2-aminopropionic acid)1 and its diastereoisomer, enduracididine 2, are two nonproteinogenic amino acids isolated in 1968 from Streptomyces fungicidicus as part of a cyclopeptide the ...

Synthesis of Cyclic Guanidines via Pd-Catalyzed Alkene Carboamination

open access: yes, 2016
A new approach to the synthesis of substituted 5-membered cyclic guanidines is described. Palladium-catalyzed alkene carboamination reactions between acyclic N-allyl guanidines and aryl or alkenyl halides provide these products in good yield. This method

Detection and substitution-pattern determination of guanidines [PDF]

open access: yes, 1976
The guanidine function can be detected and its substitution pattern determined taking into account the1H-NMR signals of the N−H and N−C−H groups. Satisfactory results were obtained with mono-to penta-substituted guanidines (as picrate salts).Facultad de ...

Engineering Microbial Particles for Next‐Generation Biomedical Platforms

open access: yesAdvanced Science, EarlyView.
Microbe‐derived particles (MDPs), which include extracellular vesicles, outer membrane vesicles, inclusion bodies, polysaccharide particles, and virus‐like particles, represent a rapidly expanding category of bioinspired nanomaterials. With their natural origin, intrinsic biocompatibility, and highly programmable functionality, MDPs serve as a ...

A Phosphorylation‐Induced Micellization Switch in the Low‐Complexity Domain of TDP‐43

open access: yesAdvanced Science, EarlyView.
Phosphorylation of TAR DNA‐binding protein's 43 kDa (TDP‐43) low‐complexity domain by casein kinase 1 delta (CK1δ) acts as a molecular switch, redirecting its self‐assembly from macroscopic phase separation toward finite‐sized, spherical block‐copolymer micelles of ∼30 nm.

Synthesis and Antifungal Activity of Some New Guanidines [PDF]

open access: yes, 2014
The synthesis of some N-subsituted -N'-aryl-N"-ethyl/benzyl guanidines (II) and (III) and their precurser thiocarbamides (I) has been carried out. All these compounds have been screened in vitro for their antifungal activity against Helminthosporium ...

An Aggregation‐Induced Polymerization Poly(Disulfide)‐Drug Nanoplatform for Autoimmune Uveitis Therapy via Inhibiting the cGAS‐STING Pathway

open access: yesAdvanced Science, EarlyView.
A cationic poly(disulfide)‐drug nanoplatform (LA/DexP) was developed to treat experimental autoimmune uveitis (EAU). With potent blood‐retinal barrier penetrability, LA/DexP releases DSP in response to high ROS and scavenges cfDNA to inhibit the cGAS‐STING signaling pathway.

Lanthanum Carbonate Nanosheets Based Colloidal Hydrogel for Modulating Innate & Adaptive Tumor Immunotherapy by Augmented Cellular Pyroptosis

open access: yesAdvanced Science, EarlyView.
The Gela/decitabine/La2(CO3)3 colloidal (GDLC) hydrogel developed here could reverse the epigenetic silencing of the GSDME gene by the synergistic interaction between DAC and La3+, while concurrently activating caspase‐3, thus facilitating pyroptosis induction under the tumor microenvironment.

Structure and Biosynthesis of Mangotoxin Produced by the Plant Pathogen Pseudomonas syringae

open access: yesAngewandte Chemie, EarlyView.
The structure of mangotoxin remained elusive for over two decades. Here, mangotoxin was isolated from the native producer, Pseudomonas syringae pv. syringae, and was determined to be an alkyne‐containing dipeptide. Mangotoxin inhibited the growth of multidrug‐resistant human pathogen Klebsiella pneumoniae.
