                            Lead compounds were obtained in a high throughput screen (HTS) of angiogenin (ANG; a potent inducer of angiogenesis) enzyme activity, an RNase. One lead was shown to delay appearance of tumors in an animal tumor system, and to reduce the number of animals having tumors. Several lead compound analogs were found to be even more potent inhibitors of ANG activity compared to the original leads, and two were also found to have greater affinity for ANG than for pancreatic RNase. Other embodiments disclose a method comprising obtaining a ribonuclease inhibitor and a composition; and admixing the ribonuclease inhibitor and the composition to form an admixture, wherein a ribonuclease that may be present in the admixture is inhibited.
