SMILES

希望可以把生成后的自定义SMILES保存到自己的分子库里。而且为什么不能下载全量分子库?

Response from developer

您好,已经添加自定义分子库功能,可以将搜索到的分子点击收藏添加到分子库,会同时在收藏和分子库中出现 关于全量分子库,目前由于系统限制原因,仅支持iOS26.1以上的设备下载。

离线分子库可以有中文名吗

离线分子库可以有中文名吗

Response from developer

谢谢提问,分两块说清楚: App 内精编的 352 个分子(常见药物、维生素、神经递质、聚合物单体等)已经全部带中文名和中文简介,直接搜"阿司匹林""葡萄糖""乙酸乙酯"就能命中。 而完整分子库的 8,000 / 46 万条来自 PubChemLite 公开数据集,原始数据只有英文与 IUPAC 名称,所以目前还没有逐条中文名;这一部分可以用分子式、SMILES、InChIKey 或 PubChem CID 检索,结果同样离线可用。 给常用化合物补中文别名这件事我已经记下来了,会在后续版本里评估。如果你有特别常查的分子,欢迎告诉我具体名字,我优先补进精编库。

不错的软件

真的厉害,化学家很好的日常软件

Response from developer

谢谢你的认可!很高兴它能帮上日常工作。后续会继续打磨数据和体验,有任何建议欢迎随时告诉我。
