ABSTRACT The ultimate goal of this proposal renewal entitled, “New antifungals targeting the synthesis of fungal sphingolipids”, is to continue the optimization of our 3rd generation compounds that we generated using the previous funding cycle, with the ultimate goal to subject 1-5 compounds at the end of the renewal to preclinical studies and file an Investigational New Drug (IND) with the Food Drug Administration (FDA) for the treatment of invasive fungal infections (IFI). IFIs are increasingly responsible for serious life-threatening conditions, particularly in individuals with compromised immunity. For the past 10 years, we have been working on the research and development of a new class of antifungal agents directed against the synthesis of fungal but not mammalian sphingolipids. The initial discovery of N’-(3-bromo-6-hydroxybenzylidene)-2-methylbenzohydrazide (BHBM) as the hit compound from library screening lead us to initiate an intensive research program involving the combinatorial/parallel synthesis of BHBM derivatives and the assessment of a structure-activity relationship. This program allowed us to synthesize a 3rd-generation compounds more efficacious than the antifungals currently used in the clinic. Our 3rd-generation compounds have secured intellectual property (IP) and a start-up company (MicroRid Technologies Inc.) with licensing options was co-funded, bringing the necessary expertise to further develop these potent antifungal compounds. We now seek to optimize pharmacokinetics, toxicology properties without losing antifungal activity. We initiated the synthesis of several hundred compounds to create a 3rd generation compounds based on D13 (Aim 1) that will be assessed for antifungal activity and mechanism of action (Aim 2). A few selected compounds will be subjected to toxicology and intensive PK studies (Aim 3), and, finally, one compound will ultimately be selected for IND filing. Our experience, expertise, and ongoing effort in this area of antifungal research and the partnership between Stony Brook University, the Long Island High Tech Incubator, and MicroRid Technologies Inc. place us in a very unique position to achieve these goals.

摘要 这项题为“针对真菌鞘脂合成的新抗真菌药”的提案更新的最终目标是 继续优化我们使用上一个资金周期生成的第三代化合物， 最终目标是在临床前研究更新结束时将1-5种化合物纳入临床前研究，并提交研究性新药 (IND)与美国食品药品监督管理局（FDA）合作，用于治疗侵袭性真菌感染（IFI）。国际金融机构日益 导致严重危及生命的疾病，特别是免疫力低下的个体。在过去的10年里， 我们一直致力于研究和开发一类新的抗真菌剂， 真菌而不是哺乳动物鞘脂。N ′-（3-溴-6-羟基苯亚甲基）-2-甲基苯甲酰肼的首次发现 （BHBM）作为来自文库筛选的热门化合物，导致我们启动了一项深入的研究计划， BHBM衍生物的组合/平行合成和结构-活性关系的评估。这个程序 使我们能够合成比目前临床上使用的抗真菌药更有效的第三代化合物。 我们的第三代化合物已获得知识产权（IP）和一家初创公司（MicroRid Technologies 公司）与许可选项共同资助，带来必要的专业知识，以进一步开发这些有效的抗真菌药物， 化合物.我们现在寻求优化药代动力学、毒理学特性，同时又不失去抗真菌活性。我们发起 基于D13（目标1）合成数百种化合物以产生第三代化合物，将对其进行评估 抗真菌活性和作用机制（目的2）。一些选定的化合物将受到毒理学和密集的 PK研究（目标3），最后，最终将选择一种化合物进行IND申报。我们的经验、专业知识和 努力在这一领域的抗真菌研究和合作伙伴关系之间的斯托尼布鲁克大学，长岛高科技 孵化器和MicroRid Technologies Inc.使我们处于一个非常独特的位置来实现这些目标。
