Logáil Isteach / Cláraigh
A series of D- and L-tyrosine-chlorambucil analogs was synthesized as anticancer drugs for chemotherapy of breast cancer. The novel compounds were synthesized in good yields through efficient modifications of D- and L-tyrosine. The newly synthesized compounds were evaluated for their anticancer

Is there a relation between genetic susceptibility with cancer? A study about paraoxanase (PON1) enzyme activity in breast cancer cases.

Logáil Isteach / Cláraigh
Human serum paraoxonase 1 (PON1, EC 3.1.1.2) is a high density lipoprotein (HDL)-associated antioxidant enzyme that not only decreases oxidative stress, but it is also implicated in development of many cancers. Genetic information provides a means of identifying people who have an increased risk of

Synthesis of (99m)Tc-EC-AMT as an imaging probe for amino acid transporter systems in breast cancer.

OBJECTIVE This study was to develop a (99m)Tc-labeled alpha-methyl tyrosine (AMT) using L,L-ethylenedicysteine (EC) as a chelator and to evaluate its potential in breast tumor imaging in rodents. METHODS EC-AMT was synthesized by reacting EC and 3-bromopropyl AMT (N-BOC, ethyl ester) in

Association of inhibition of cell growth by O-phospho-L-tyrosine with decreased tyrosine phosphorylation.

We have previously demonstrated that O-phospho-L-tyrosine (P-Tyr), a substrate for a wide range of PTPases, inhibits the growth of human renal cell carcinoma and human breast cancer cell lines and suppresses EGF-mediated EGFR tyrosine phosphorylation. We now show that P-Tyr inhibited the growth of
The functional components in soymilk may vary depending upon the fermentation process. A fermented soymilk product (FSP) obtained by incubation with the microorganisms of intestinal microflora was found to reduce the risk of breast cancer. Guided by the inhibitory activities against breast cancer

Development of (99m)Tc-EC-tyrosine for early detection of breast cancer tumor response to the anticancer drug melphalan.

Ní féidir ach le húsáideoirí cláraithe ailt a aistriú
Logáil Isteach / Cláraigh
OBJECTIVE Radiolabeled tyrosine analogues that have been successfully used in tumor imaging accumulate in tumor cells via an upregulated L-type amino acid transporter system. The anticancer drug melphalan is an L-type amino acid transporter substrate. Therefore, radiolabeled tyrosine analogues may

Exploring the synthesis and anticancer potential of L-tyrosine-platinum(II) hybrid molecules.

Logáil Isteach / Cláraigh
The search for new specific chemotherapeutic drugs designed to minimize the toxic side effects resulting from chemotherapy is still a subject of intense research. The objective of the current study was to design a non-steroidal-platinum(II) derivative that would target the estrogen receptor alpha

Multistimuli-Responsive Amphiphilic Poly(ester-urethane) Nanoassemblies Based on l-Tyrosine for Intracellular Drug Delivery to Cancer Cells.

Logáil Isteach / Cláraigh
Multistimuli-responsive l-tyrosine-based amphiphilic poly(ester-urethane) nanocarriers were designed and developed for the first time to administer anticancer drugs in cancer tissue environments via thermoresponsiveness and lysosomal enzymatic biodegradation from a single polymer platform. For this

PET with O-(2-18F-Fluoroethyl)-L-Tyrosine in peripheral tumors: first clinical results.

O-(2-18F-Fluoroethyl)-L-Tyrosine (18F-FET) PET has shown promising results in brain tumor diagnosis. The aim of this prospective study was to evaluate 18F-FET PET in comparison with 18F-FDG PET in patients with peripheral tumors. METHODS Forty-four consecutive patients with suspected malignant
l-type amino acid transporter 1 (LAT1) is an amino acid transporter that is overexpressed in several types of cancer and, thus, it can be a potential target for chemotherapy. The objectives of this study were to (a) synthesize LAT1-targeted chlorambucil derivatives and (b) evaluate their

Thirteen new ruthenium amino acid complexes were synthesized and characterized. They were obtained by the reaction of α-amino acids (AA) with [RuCl2(P-P)(N-N)], where P-P=1,4-bis(diphenylphosphino)butane (dppb) or 1,3-bis(diphenylphosphino)propane (dppp) and N-N=4,4'-dimethyl-2,2'-bipyridine
Amino acid transport is an attractive target for oncologic imaging. Despite a high demand of cancer cells for cationic amino acids, their potential as PET probes remains unexplored. Arginine, in particular, is involved in a number of biosynthetic pathways that significantly influence carcinogenesis
Polypeptide micelles, though having been proved to be an appealing nanoplatform for cancer chemotherapy, are met with issues like inefficient drug encapsulation, gradual drug release, and low tumor cell selectivity and uptake. Here, we report on cRGD-decorated, small-sized, robust, and

Colloidal gels are three-dimensional networks of microgel particles and can be utilized to design microtissues where the differential adhesive interactions between the particles and cells, guided by their surface energetics, are engineered to spatially assemble the cellular and colloidal components
BACKGROUND (18)F-labeled amino acids are important PET radiotracers for molecular imaging of cancer. This study describes synthesis and radiopharmacological evaluation of 2-amino-5-(4-[(18)F]fluorophenyl)pent-4-ynoic acid ([(18)F]FPhPA) as a novel amino acid radiotracer for oncologic
