Fluorine-Substituted Pyrrolo[2,3â<i>d</i>]Pyrimidine Analogues with Tumor Targeting via Cellular Uptake by Folate Receptor α and the Proton-Coupled Folate Transporter and Inhibition of <i>de Novo</i> Purine Nucleotide Biosynthesis
Novel
fluorinated 2-amino-4-oxo-6-substituted pyrroloÂ[2,3-<i>d</i>]Âpyrimidine analogues <b>7</b>â<b>12</b> were
synthesized and tested for selective cellular uptake by folate
receptors (FRs) α and ÎČ or the proton-coupled folate transporter
(PCFT) and for antitumor efficacy. Compounds <b>8</b>, <b>9</b>, <b>11</b>, and <b>12</b> showed increased <i>in vitro</i> antiproliferative activities (âŒ11-fold)
over the nonfluorinated analogues <b>2</b>, <b>3</b>, <b>5</b>, and <b>6</b> toward engineered Chinese hamster ovary
and HeLa cells expressing FRs or PCFT. Compounds <b>8</b>, <b>9</b>, <b>11</b>, and <b>12</b> also inhibited proliferation
of IGROV1 and A2780 epithelial ovarian cancer cells; in IGROV1 cells
with knockdown of FRα, <b>9</b>, <b>11</b>, and <b>12</b> showed sustained inhibition associated with uptake by PCFT.
All compounds inhibited glycinamide ribonucleotide formyltransferase,
a key enzyme in the <i>de novo</i> purine biosynthesis pathway.
Molecular modeling studies validated <i>in vitro</i> cell-based
results. NMR evidence supports the presence of an intramolecular fluorineâhydrogen
bond. Potent <i>in vivo</i> efficacy of <b>11</b> was
established with IGROV1 xenografts in severe compromised immunodeficient
mice

Tumor Targeting with Novel Pyridyl 6âSubstituted Pyrrolo[2,3â<i>d</i>]Pyrimidine Antifolates via Cellular Uptake by Folate Receptor α and the Proton-Coupled Folate Transporter and Inhibition of <i>De Novo</i> Purine Nucleotide Biosynthesis
Tumor-targeted specificities of 6-substituted
pyrroloÂ[2,3-<i>d</i>]Âpyrimidine analogues of <b>1</b>, where the phenyl
side-chain is replaced by 3âČ,6âČ (<b>5</b>, <b>8</b>), 2âČ,5âČ (<b>6</b>, <b>9</b>),
and 2âČ,6âČ (<b>7</b>, <b>10</b>) pyridyls,
were analyzed. Proliferation inhibition of isogenic Chinese hamster
ovary (CHO) cells expressing folate receptors (FRs) α and ÎČ
were in rank order, <b>6</b> > <b>9</b> > <b>5</b> > <b>7</b> > <b>8</b>, with <b>10</b> showing
no activity, and <b>6</b> > <b>9</b> > <b>5</b> > <b>8</b>, with <b>10</b> and <b>7</b> being
inactive,
respectively. Antiproliferative effects toward FRα- and FRÎČ-expressing
cells were reflected in competitive binding with [<sup>3</sup>H]Âfolic
acid. Only compound <b>6</b> was active against proton-coupled
folate receptor (PCFT)-expressing CHO cells (âŒ4-fold more potent
than <b>1</b>) and inhibited [<sup>3</sup>H]Âmethotrexate uptake
by PCFT. In KB and IGROV1 tumor cells, <b>6</b> showed <1
nM IC<sub>50</sub>, âŒ2â3-fold more potent than <b>1</b>. Compound <b>6</b> inhibited glycinamide ribonucleotide
formyltransferase in <i>de novo</i> purine biosynthesis
and showed potent <i>in vivo</i> efficacy toward subcutaneous
IGROV1 tumor xenografts in SCID mice
