Previous findings suggesting that 5,10-dialkyl-substituted derivatives of 5,10-dideazaaminopterin warranted study as potential antifolates prompted synthesis of 10-ethyl-5-methyl-5,10- dideazaaminopterin (12a). The key step in the synthetic route to

The epidermal growth factor receptor tyrosine kinase inhibitor ZD1839 (Iressa) markedly potentiates the efficacy of many cytotoxic agents against several human cancer xenografts, irrespective of tumor EGFR expression levels. We subsequently investiga

10-propargyl-10-deazaaminopterin (PDX) has superior antitumor efficacy in mouse xenograft models, likely attributable to increased uptake by the RFC-1 folate transporter and greater intracellular polyglutamylation. In a previous Phase I trial, stomat

CPT-11, a DNA topoisomerase I inhibitor, has demonstrated clinical activity in colorectal cancer. Flavopiridol, a cyclin-dependent kinase inhibitor, is rapidly emerging as a chemotherapy modulator. To enhance the therapeutic index of CPT-11 in colon

Studies described here sought to evaluate the therapeutic potential of a new 10-deazaaminopterin analogue, 10-propargyl-10-deazaaminopterin (PDX), alone and in combination with platinum compounds in the treatment of human pleural mesothelioma. In vit

Analysis of independently isolated clones from a mouse liver cDNA library identified a splice variant of gamma-GH mRNA with novel nucleotide sequence at the 5' end. Genomic sequencing now shows that this variant (variant II) incorporates two new alte

The antifolate edatrexate has shown moderate activity against cancers of the head and neck and non-small cell lung cancer, as has cisplatin. Edatrexate demonstrates synergy with cisplatin in transplanted tumor models. This Phase I study was designed

The blockade of epidermal growth factor receptor (EGFR) function with monoclonal antibodies has major antiproliferative effects against human tumors in vivo. Similar antiproliferative effects against some of these same tumors have also been observed

Folate is an essential micronutrient that, in mammals, must be obtained from exogenous sources via intestinal absorption. Previous studies have characterized different aspects of the mechanism of the intestinal folate uptake process. Much less, howev
