项目摘要

DESCRIPTION (provided by applicant): There is a significant interest and need for developing new immunostimulatory adjuvant molecules that stimulate potent immune responses. To date, the only immunostimulatory adjuvant molecule that has been approved for human use is the Toll-like Receptor (TLR) 4 agonist, monophosphoryl lipid A (MPL). Other immunostimulatory adjuvant molecules such as poly I:C, a synthetic double stranded RNA mimic (TLR3), resiquimod, a synthetic single stranded RNA mimic (TLR7/8) or CpG, a DNA oligonucleotide (TLR9), have been in clinical development for a number of disease indications. A new class of immunostimulatory adjuvant molecules, cyclic dinucleotides (CDNs), have recently been shown to exert potent immunostimulatory properties through activation of an internal receptor called the STimulator of INterferon Genes (STING). In this project, we propose to optimize a small molecule immunostimulatory adjuvant, tucaresol, which we have synthesized with a "lipid tail" to facilitate formulation in the VesiVax(r) vaccine and adjuvant platform technology. We will synthesize lipidated tucaresol (LT) derivatives and prepare VesiVax(r) LT formulations with a model recombinant protein antigen (i.e., gD3PEPcD-HD) which we have shown to provide protective immune responses in our well-characterized mouse model of intravaginal HSV2 challenge.

描述（由申请人提供）：对开发刺激有效免疫应答的新免疫刺激佐剂分子存在显著的兴趣和需求。迄今为止，唯一被批准用于人类的免疫刺激佐剂分子是Toll样受体（TLR）4激动剂，单磷酰脂质A（MPL）。其他免疫刺激佐剂分子，如聚I：C，一种合成的双链RNA模拟物（TLR 3），瑞喹莫特，一种合成的单链RNA模拟物（TLR 7/8）或CpG，一种DNA寡核苷酸（TLR 9），已经在临床开发中用于许多疾病适应症。一类新的免疫刺激佐剂分子，环状二核苷酸（CDN），最近已被证明通过激活称为干扰素基因（STING）的内部受体发挥有效的免疫刺激特性。在这个项目中，我们建议优化一种小分子免疫刺激佐剂，妥卡雷琐，我们已经合成了一个“脂质尾”，以促进VesiVax（r）疫苗和佐剂平台技术的配制。我们将合成脂化妥卡雷琐（LT）衍生物，并用模型重组蛋白抗原（即，gD 3 PEPcD-HD），我们已经证明其在我们的阴道内HSV 2攻击的良好表征的小鼠模型中提供保护性免疫应答。
