it has been observed that lung cancer either non-small cell or small cell is responsible for eye metastases. this form of metastases in several cases was the first manifestation of the disease and further investigation led to the diagnosis of the underlying malignancy. both types of lung cancer are equally responsible for this demonstration. furthermore; both chemotherapy and tyrosine kinase in...

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...

an efficient synthesis of polyhydroquinoline derivatives is achieved via hantzsch condensation reaction between aldehydes, dimedone, ethyl acetoacetate and ammonium acetate in the presence of catalytic amount of sfhs in ethanol. this method gives remarkable advantages such as shorter reaction time, simple workup procedure and good to excellent yields. furthermore the catalyst can be recovered c...

The anti-allergic drug tranilast (TNL) reportedly exhibits inhibitory activity against epithelial-mesenchymal transition (EMT) at high concentrations. Herein, we synthesized a new hybrid molecule, tyrosine-conjugated TNL having propyl linker (TNL-T), which is expected to increase anti-EMT by enhancing intracellular delivery through an amino acid transporter expressed in cancer cells. of TNL-T w...

Tyrosine-containing pharmaceuticals’ (TPh) potential to inhibit SARS CoV-2 3-chymotrypsin-like proteases (3CLpro) and nonstructural protein 16 (NSP16) has been explored using docking studies, molecular dynamics simulations, density functional theory. The TPh with FDA approval showed excellent contact the active site pockets of 3CLpro NSP16. Their binding affinity scores ranged from −5.8 −4.9 kc...

Acute tyrosine ingestion is thought to improve aerobic endurance, muscle strength and endurance, and anaerobic power of men undergoing severe physiologic stress. In a double-blind, crossover study, 20 men (32 ± 1 y old) underwent 2 loadcarriage treadmill sessions, 1 after taking tyrosine (150 mg/kg L-crystalline tyrosine) and 1 after taking placebo. Tyrosine dosage was based on subject weight a...
