Abstract
Parasitic roundworms (nematodes) cause destructive diseases, and immense suffering in humans and other animals around the world. The control of these parasites relies heavily on anthelmintic therapy, but treatment failures and resistance to these drugs are widespread. As efforts to develop vaccines against parasitic nematodes have been largely unsuccessful, there is an increased focus on discovering new anthelmintic entities to combat drug resistant worms. Here, we employed thermal proteome profiling (TPP) to explore hit pharmacology and to support optimisation of a hit compound (UMW-868), identified in a high-throughput whole-worm, phenotypic screen. Using advanced structural prediction and docking tools, we inferred an entirely novel, parasite-specific target (HCO_011565) of this anthelmintic small molecule in the highly pathogenic, blood-feeding barber’s pole worm, and in other socioeconomically important parasitic nematodes. The “hit-to-target” workflow constructed here provides a unique prospect of accelerating the simultaneous discovery of novel anthelmintics and associated parasite-specific targets.

Abstract
BACKGROUND Angiogenesis plays a crucial role in the progression and metastasis of malignant solid tumors. In many types of cancer, including neuroblastoma, high tumor vascularity correlates with poor outcome. Recently, a number of angiogenic inhibitors have been identified that had antitumor activity in preclinical studies. PROCEDURE To investigate the effect of the antiangiogenic agent TNP-470 on neuroblastoma tumor growth, we treated nude mice with TNP-470 after they were inoculated subcutaneously with 5 x 10(6) cells from the MYCN-amplified, human neuroblastoma cell line NBL-W-N. RESULTS TNP-470 did not significantly affect tumor growth when it was administered to mice with large tumors (>600 mm3). However, when TNP-470 was administered in the setting of microscopic disease 12 hr following tumor cell inoculation, treated mice had a significantly improved tumor-free survival at 12 weeks (P < 0.001), and overall survival at 45 weeks (P < 0.001), compared to control animals. CONCLUSIONS Our studies suggest that TNP-470 treatment may be most effective if it is administered in the setting of microscopic disease. We speculate that TNP-470 may inhibit neuroblastoma growth in children if treatment is initiated following intensive multimodality therapy, when residual disease is minimal.

Abstract
Angiogenesis plays an important role in the growth and metastasis of malignant tumors. We have previously reported that in children with neuroblastoma (NB), tumor vascularity directly correlates with metastatic disease, MYCN amplification, and poor outcome. The angiogenesis inhibitor TNP-470 has been shown to reduce the rate of NB growth in rodents with macroscopic tumors without ultimately impacting survival. To investigate whether TNP-470 could more effectively inhibit NB growth in animals with a low tumor burden, we treated 30 nude mice with minimal disease with this angiogenesis inhibitor (supplied by TAP Pharmaceuticals, Inc.). Therapy was initiated before tumors were clinically evident after s.c. inoculation of 5 x 10(6) cells from the MYCN-amplified NB cell line NBL-W-N. TNP-470 was administered 3 days/week, and after 12 weeks of treatment, 53% of the treated mice remained tumor free, whereas 100% of the control mice developed tumors (P < 0.0001). To further assess the relationship between the efficacy of TNP-470 treatment and tumor burden, TNP-470 was also administered s.c., 3 days/week, to mice with clinically evident small (<400 mm3; n = 15) and large (>400 mm3; n = 11) tumors. For animals with small tumors, the mean rate of growth was significantly decreased in the treated mice compared to the controls (P = 0.02). In contrast, there was no difference in the mean rate of tumor growth between animals with large tumors treated with TNP-470 and controls (P = 0.64). Our studies demonstrate that the effectiveness of TNP-470 inversely correlates with tumor burden. We speculate that TNP-470 may most effectively inhibit NB tumor growth in children with a low tumor burden.
