the carbodiimide-generated derivatives of aminopterin , folate , and p-aminobenzoylglutamate were also irreversible inhibitors of methotrexate transport , and their relative effectiveness paralleled the ability of the parent compounds ( aminopterin greater than methotrexate greater than folate greater than p-aminobenzoylglutamate ) to act as reversible transport inhibitors .
