    Fluorine-Substituted Pyrrolo[2,3‑<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 pyrrolo­[2,3-<i>d</i>]­pyrimidine analogues <b>7</b>–<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 (∌11-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 fluorine–hydrogen bond. Potent <i>in vivo</i> efficacy of <b>11</b> was established with IGROV1 xenografts in severe compromised immunodeficient mice

    Tumor-targeted specificities of 6-substituted pyrrolo­[2,3-<i>d</i>]­pyrimidine analogues of <b>1</b>, where the phenyl side-chain is replaced by 3â€Č,6â€Č (<b>5</b>, <b>8</b>), 2â€Č,5â€Č (<b>6</b>, <b>9</b>), and 2â€Č,6â€Č (<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]­folic acid. Only compound <b>6</b> was active against proton-coupled folate receptor (PCFT)-expressing CHO cells (∌4-fold more potent than <b>1</b>) and inhibited [<sup>3</sup>H]­methotrexate uptake by PCFT. In KB and IGROV1 tumor cells, <b>6</b> showed <1 nM IC<sub>50</sub>, ∌2–3-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
