Trans-cinnamic acid and p-coumaric are valuable intermediates in the synthesis of flavonoids widely employed food, flavor pharmaceutical industries. These products can be produced by deamination L-phenylalanine L-tyrosine catalyzed phenylalanine ammonia lyase or tyrosine lyase. Phenylalanine ammonia-lyase (PAL, EC 4.3.1.5) from Rhodotorula glutinis do not exhibit strong substrate specificity co...

Reactive oxygen and nitrogen species (RONS), including 3-nitro-l-tyrosine, play a dual role in human health, inducing oxidative damage regulating cellular functions. Early accurate detection of such molecules, as L-tyrosine urine, can serve critical biomarkers for various cancers. In this study, we aimed to enhance the electrochemical these molecules through synthesis La2Sn2O7/f-HNT nanocomposi...

Suppression of Akt (Protein kinase B) has been implicated in schizophrenia, the effect which has been documented to be reversed by tyrosine phosphatase inhibition. T hus, present study has been designed to study the effect of sodium orthovanadate, a tyrosine phosphatase inhibitor, on protracted methionine administration induced schizophrenia like behavior in rats.   Schizophrenia...

Novel anthracene-based Schiff base derivative (4-(anthracen-9-ylmethylene) amino)-5-phenyl-4H-1,2,4-triazole-3-thiol; AT2) is synthesized and utilized as an aggregation-induced emission-enhancement (AIEE) active probe to detect Zn2+ Tyrosine. Ultraviolet-visible absorption/photoluminescence (UV-vis/PL) spectroscopy studies on the AIEE property of AT2 (in ethanol) with increasing water fractions...

Biogenic amines play an important role in brain metabolism and functioning, participation synaptic transmission as neurotransmitters neuromodulators (dopamine, serotonin, histamine others). Catecholamines are formed from the essential amino acid phenylalanine by hydroxylating it to tyrosine with enzyme phenylalanine-4-hydroxylase, which is subsequently converted dioxyphenylalanine (DOPA) tyrosi...

Lignin is an underutilized sustainable source of aromatic compounds. To valorize the low-value lignin monomers, we proposed efficient strategy, involving enzymatic conversion from trans-p-hydroxycinnamic acids to generate valued-added canonical and non-canonical amino acids. Among them, β-amino are recognized as building blocks for bioactive natural products pharmaceutical ingredients due their...

the development and discovery of new anticancer agents is one of the main goals in medicinal chemistry. the conventional anticancer drugs are concomitant with high incidence of unpleasant side effects like severe gastrointestinal side effects and bone marrow suppression. in recent years, various selective anticancer agents have been emerged like dasatinib. the exact mechanism of dasatinib is th...

long-term potentiation (ltp) is a process that certain types of synaptic stimulation lead to a long-lasting enhancement in the strength of synaptic transmission. studies in recent years indicate the importance of molecular pathways in the development of memory and learning. tropomyosin receptor kinase b (trkb) is a member of the neurotrophin receptor tyrosine kinase family, that its ligand is b...

Sunitinib is an oral tyrosine kinase inhibitor which prevents tumor growth and metastatic progression. It was approved for treatment of advanced renal cell cancer, gastrointestinal stromal tumor and advanced pancreatic neuroendocrine tumors. It has several adverse reactions on multi organ systems including hematologic system. Although the neutropenia and thrombocytopenia commonly happens as Gra...
