Identification of isoform-specific histone deacetylase inhibitors (HDACi) is a significant advantage to overcome the adverse side effects of pan-HDACi for the treatment of various diseases, including cancer. We have designed, and synthesized novel 1,3,4 oxadiazole with glycine/alanine hybrids as
BACKGROUND
This paper reports the synthesis and labeling of (18)F alanine derivatives. We also investigate their biological characteristics as potential tumor imaging agents mediated by alanine-serine-cysteine preferring (ASC) transporter system.
METHODS
Three new (18)F alanine derivatives were
Glucose and alanine metabolism were investigated in non-tumor-bearing (NTB) and tumor-bearing (TB) male F344 rats after a 24-hr fast and during the infusion of either 0.9% NaCl solution or glucose at 0.67 or 2.35 mg per 100 g total body weight per min. During 0.9% NaCl solution infusion, the plasma
Purpose: The aim of this study was to evaluate the prognostic value of the aspartate transaminase/alanine transaminase (AST/ALT) ratio in a large Chinese cohort surgically treated for localized upper tract urothelial carcinoma (UTUC) using propensity score matching (PSM) analysis.
The effect of Picibanil, a streptococcal agent, on the development of liver injury after operations for urogenital cancer was studied retrospectively in the light of serum alanine aminotransferase (ALT) activity. The series comprised 32 cases receiving Picibanil and 33 controls with otherwise
The chymotrypsin-like serine protease inhibitor, succinyl-alanine-alanine-proline-phenylalanine chloromethyl ketone (AAPF(CMK)), has been shown to have anticarcinogenic activity in a number of model systems and to be relatively selective for a nuclear protease. This inhibitor also has substantial
β-Alanine is a non-essential amino acid and presents as a major component of various sports supplements. It is a non-proteogenic amino acid, formed in vivo by degradation of carnosine, anserine, balenine, and dihydrouracil. The present study was aimed at investigating the anti-tumor effects of
Biologic image guided radiotherapy (RT) with escalated doses to tumour sub volumes challenges today's RT dose planning and delivery systems. In this phantom study, we verify the capability of a clinical dose planning and delivery system to deliver an 18F-FDG-PET based dose painted treatment plan to
In tissue cultures of C-57 black mouse heart and sarcoma T-241, beta-2-thienyl-DL-alanine acts specifically as a phenylalanine antagonist. Heart cultures can transaminate between beta-2-thienyl-DL-alanine and phenylpyruvate to form L-phenylalanine and thus block the toxic action of the remaining
Emerging evidence implicates myristoylated alanine-rich C-kinase substrate (MARCKS), a major substrate of protein kinase C (PKC), in a critical role for cancer development and progression. MARCKS is tethered to the plasma membrane but can shuttle between the cytosol and plasma membrane via the
OBJECTIVE
The goal of this study is to assess the interactions among alcohol consumption, cigarette smoking, and aspartate aminotransferase (AST) / alanine aminotransferase (ALT) ratios on esophageal cancer.
METHODS
Alcohol and the risk of incidence and death from esophageal cancer were examined in
Herein, we report the straightforward synthesis, photoluminescent properties, and cell imaging studies of d-mannose and l-alanine functionalized silicon nanocrystals (SiNCs). Tailoring nanocrystal surface functionalization is essential to interfacing SiNCs with their environment and rendering them
Oxadiazole is a heterocyclic compound containing an oxygen atom and two nitrogen atoms in a five-membered ring. Of the four oxadiazoles known, 1,3,4-oxadiazole has become an important structural motif for the development of new drugs and the compounds containing 1,3,4-oxadiazole cores have a broad
Glutamine metabolism, described as major energy and building blocks supply to cell growth, has gained great attention. Alanine-Serine-Cysteine Transporter (ASCT2), which belongs to solute carried (SLC) family transporters and is encoded by the SLC1A5 gene serves as a significant role for glutamine
BACKGROUND
Glutamine is an essential source of energy, metabolic substrates, and building block for supporting tumor proliferation. Previously, (2S,4R)-4-[18F]fluoroglutamine (4F-Gln) was reported as a glutamine-related metabolic imaging agent. To improve the in vivo kinetics of this radiotracer,
