The platform-independent software package consisting of the oligonucleotide mass assembler (OMA) and the oligonucleotide peak analyzer (OPA) was created to support the analysis of oligonucleotide mass spectra. It calculates all theoretically possible fragments of a given input sequence and annotates it to an experimental spectrum, thus, saving a large amount of manual processing time. The software performs analysis of precursor and product ion spectra of oligonucleotides and their analogues comprising user-defined modifications of the backbone, the nucleobases, or the sugar moiety, as well as adducts with metal ions or drugs. The ability to expand the library of building blocks and to implement individual structural variations makes it extremely useful for supporting the analysis of therapeutically active compounds. The functionality of the software tool is demonstrated on the examples of a platinated double-stranded oligonucleotide and a modified RNA sequence. Experiments also reveal the unique dissociation behavior of platinated higher-order DNA structures.
该平台独立的软件包由寡核苷酸质量组装器（OMA）和寡核苷酸峰分析器（OPA）组成，旨在支持寡核苷酸质谱分析。它计算给定输入序列的所有理论可能片段，并将其注释到实验谱中，从而节省大量手动处理时间。该软件对包含用户定义的骨架、碱基或糖部分修饰以及与金属离子或药物的加合物的寡核苷酸及其类似物的前体和产物离子谱进行分析。扩展构建块库和实现个别结构变化的能力使其在支持治疗活性化合物的分析方面非常有用。该软件工具的功能通过顺铂化双链寡核苷酸和修饰的 RNA 序列的实例得到证明。实验还揭示了顺铂化高级 DNA 结构的独特解离行为。
