Angiogenesis: A less bitter pill

Patrick Goymer

The broad-spectrum angiogenesis inhibitor TNP-470 is a potent suppressor of tumour growth and metastasis, but its use is limited because it requires lengthy bouts of parenteral administration. To remove this limitation, Folkman and colleagues have enclosed TNP-470 in nanopolymeric micelles and shown that in mice it retains the potency of the free drug.
