（重定向自Deoxypyridoxine）
4-Deoxypyridoxine is a vitamin B6 antagonist. It may be toxic to developing embryos since it can have negative effects on collagen and elastin during development. The presence of this compound can produce vitamin B6 deficiency, which suppresses the immune system. This immunosuppression can be beneficial in animal models of Trichinella spiralis infections.
