Targeting the tumor-associated folate receptor with an 111In-DTPA conjugate of pteroic acid[Pubmed: 15898791]
The cell membrane folate receptor is a potential molecular target for tumor-selective drug delivery. To probe structural requirements for folate receptor targeting with low molecular weight radiometal chelates, specifically the role of the amino acid fragment of folic acid (pteroylglutamic acid) in mediating targeting selectivity, the amide-linked conjugate pteroyl-NHCH(2)CH(2)OCH(2)CH(2)OCH(2)CH(2)NH-DTPA was prepared by a three-step procedure from Pteroic acid, 2,2'-(ethylenedioxy)-bis(ethylamine), and t-Bu-protected DTPA. This conjugate, 1-{2-[2-[(2-(biscarboxymethyl-amino)ethyl)-carboxymethyl-amino]ethyl]-carboxymethyl-amino}-acetylamino-3,6-dioxa-8-pteroylamino-octane (1), was employed for synthesis of the corresponding (111)In(III) radiopharmaceutical. Following intravenous administration to athymic mice, the (111)In complex of 1 was found to selectively localize in folate receptor-positive human KB tumor xenografts and to afford prolonged tumor retention of the (111)In radiolabel (5.4 +/- 0.8, 5.6 +/- 1.1, and 3.6 +/- 0.6% of the injected dose per gram of tumor at 1, 4, and 24 h, respectively). The observed tumor localization was effectively blocked by co-administration of folic acid with the (111)In-1 complex, consistent with a folate receptor-mediated targeting process. In control studies, tumor targeting with this Pteroic acid conjugate appears as effective as that seen using (111)In-DTPA-folate, a radiopharmaceutical that has progressed to clinical trials for detection of folate receptor-expressing gynecological tumors.

Storage: Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).

Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

After receiving: The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

Activation of folypolyglutamate synthetase by pteroic acid[Pubmed: 3840051]
The glutamylation of methotrexate catalyzed by beef liver folypolyglutamate synthetase (FPGS) is activated by addition of Pteroic acid. Pteroic acid causes greater stimulation of FPGS, including glutamylation of tetrahydrofolate, at neutral pH values (i.e., below the pH optimum of 8.4). We have attributed this activation to a conformational change of FPGS induced by Pteroic acid.

Synthesis and biological activity of 10-thia-10-deaza analogs of folic acid, pteroic acid, and related compounds[Pubmed: 808608]
The 10-thia analogs of Pteroic acid, folic acid, their esters, and their 4-amino analogs were synthesized through a reaction sequence involving, as a key step, the condensation of 2-amino-3-cyano-5-chloromethylpyrazine with appropriately substituted thiols. The abilities of the products to inhibit the growth of methotrexate (MTX)-sensitive and MTX-resistant microorganisms were investigated as were their abilities to inhibit dihydrofolic acid reductase and thymidylic acid synthetase. Several compounds had high activity.
