The invention relates to compounds that interact with heparanase, uses in heparanase screening, uses in in vitro and in vivo imaging (e.g., positron emission tomography (PET) and magnetic resonance imaging (MRI)), methods of synthesis, methods of modulating heparanase activity, and methods of treating disease and disorders associated with heparanase. The compounds of the invention are also useful in treating one or more diseases or disorders associated with the function of heparanase.

6-Thio derivatives of D-luciferin, also referred to as D-thioluciferins, having the general structure of Formula (I) are provided. Methods for synthesising D-luciferin, its derivatives, and their related 2-cyanobenzothiazole precursors are also provided. These compounds are commercially valuable due to their application in optical imaging, particularly in bioluminescence imaging.
On the use of peroxy-caged luciferin (PCL-1) probe for bioluminescent detection of inflammatory oxidants in vitro and in vivo – Identification of reaction intermediates and oxidant-specific minor products
first used to image hydrogenperoxide in living systems (Van de Bittner et al., 2010 [9]). Recently this probe was shown to react with peroxynitrite more potently than with hydrogenperoxide (Sieracki et al., 2013 [11]) and was suggested to be a more suitable probe for detecting peroxynitrite under in vivo conditions. In this work, we investigated in detail the products formedfrom the reaction between
过氧笼式荧光素(PCL-1)探针首先用于在生物系统中对过氧化氢成像(Van de Bittner等人,2010 [9])。最近,该探针与过氧亚硝酸盐的反应比与过氧化氢的反应更有效(Sieracki等,2013 [11]),被认为是在体内条件下检测过氧亚硝酸盐的更合适的探针。在这项工作中,我们详细研究了PCL-1与过氧化氢,次氯酸盐和过氧亚硝酸盐之间的反应形成的产物。HPLC分析表明,过氧化氢与PCL-1反应缓慢,形成萤光素是唯一的产物。次氯酸盐与PCL-1的次氯酸盐反应产生的萤光素明显减少,因为次氯酸盐将萤光素氧化成氯化的萤光素。PCL-1与过氧亚硝酸盐之间的反应由主要途径和次要途径组成。主要途径产生萤光素,次要途径产生自由基介导的硝化萤光素。自由基中间体的特征是自旋俘获。我们得出的结论是,除了在体内进行生物发光外,对氯化和硝化产物的监测还将有助于确定负责源自PCL-1的生物发光的氧化剂的性质。
