Novel scaffolds are of uttermost importance for the discovery of functional material. Three different heterocyclic scaffolds easily accessible from isocyanoacetaldehyde dimethylacetal 1 by multicomponent reaction (MCR) are described. They can be efficiently synthesized by a Ugi tetrazole multicomponent reaction of 1. We discuss the synthesis, 3D structures, and other physicochemical properties.

The coordination of 2-pyridyltetrazolate and ortho-xylene-linked bis(NHC)cyclophane to Pt(II) yielded a novel complex characterised by enhanced pure deep-blue emission, whose intensity can be modulated via methylation of the tetrazole ring.

methanesulfonic acid (msa) was found to be an efficient catalyst for the synthesis of 1-substituted-1h-1,2,3,4-tetrazoles. a series of 1-substituted tetrazole compounds were synthesized from the reaction of various primary amines, sodium azide and triethyl orthoformate in the presence of catalytic amounts of msa at room temperature. in this protocol, some of the tetrazole derivatives were synth...

SUMMARY A smart polymeric nanoparticle (SPN) with matrix metalloproteinase-7 (MMP-7) dependent proximityactivated targeting (PAT) has been designed and tested for targeted intracellular siRNA delivery to MMP-7 overexpressing tissues (i.e., tumor metastases). With this novel PAT-SPN design, a removable PEG corona mitigates cytotoxicity and nonspecific uptake in normal tissues. Exposure to MMP (i...

A purification scheme for the enzyme phosphinothricin-N-acetyltransferase (PAT) origi­ nating from Streptomyces viridochromogenes {pat-gene product from Streptomyces virido­ chromogenes) and mediating herbicide resistance to transgenic plants was developed. The enzyme was isolated from a transformed and overproducing Escherichia coli strain. With a combination of ammonium sulfate fractionation,...

Photoacoustic tomography (PAT) combines rich optical absorption contrast with the high spatial resolution of ultrasound at depths in tissue. The high scalability of PAT has enabled anatomical imaging of biological structures ranging from organelles to organs. The inherent functional and molecular imaging capabilities of PAT have further allowed it to measure important physiological parameters a...

Repurposing existing drugs not only accelerates drug discovery but rapidly advances clinical therapeutic strategies. In this article, we identified potassium antimonyl tartrate (PAT), an antiparasitic drug, as a novel agent to block angiogenesis by screening US Food and Drug Administration-approved chemical drugs. By comparing the cytotoxicity of PAT in various nonsmall-cell lung cancer (NSCLC)...

trauma continues to be the most frequent cause of death in the first four decades of life that is a main public health problem in some countries. we perform an epidemiological study of penetrating abdominal trauma (pat). we describe epidemiological of patients in pat. in a cross-sectional study we evaluated epidemiological pat admitted to emergency department in six general hospitals in tehran....
