Structure-Based Design and Synthesis of Novel Inhibitors Targeting HDAC8 from Schistosoma mansoni for the Treatment of Schistosomiasis
摘要:
Schistosomiasis is a major neglected parasitic disease that affects more than 265 million people worldwide and for which the control strategy consists of mass treatment with the only available drug, praziquantel. In this study, a series of new benzohydroxamates were prepared as potent inhibitors of Schistosoma mansoni histone deacetylase 8 (smHDAC8). Crystallographic analysis provided insights into the: inhibition mode of smHDAC8 activity by these 3-amidobenzohydroxamates. The newly designed inhibitors were evaluated in screens for enzyme inhibitory activity against schistosome and human HDACs. Twenty-seven compounds were found to be active in the nanomolar range, and some of them showed selectivity toward smHDAC8 over the major human HDACs (I and 6). The active benzohydroxamates were additionally screened for lethality against the schistosome larval stage using a fluorescence-based assay. Four of these showed significant dose-dependent killing of the schistosome larvae and markedly impaired egg laying of adult worm pairs maintained in culture.
The use of 3-amino-4-n-propoxybenzyl alcohol as a nonnutritive sweetener for foods, beverages and the like is disclosed.

A therapeutic method is provided to treat neutrophil-associated pulmonary diseases, such as chronic obstructive pulmonary disease, by locally administering to a mammal in need of such treatment, an effective amount of a topical anesthetic, such as lidocaine, or a pharmaceutically acceptable salt thereof.
The invention provides a therapeutic method for treating at least one symptom of a neurological disorder or disease such as Alzheimer's disease in a mammal, such as a human, wherein the toxicity of a pathogen of β amyloid peptide and/or glutamate in mammalian cells is implicated and inhibition of the subsequently-induced pathological pathways is desired comprising administering to a mammal in need of such therapy, an effective amount of an N-arylamide or an (N-aminoalkyl)benzamide, including pharmaceutically acceptable salts thereof.
