PharmaAI Skill

智能药物发现工作流,整合数据增强、分子性质预测、毒性预测、ADMET预测和虚拟筛选。

核心功能

1. 分子毒性预测

  • hERG心脏毒性: 预测QT间期延长风险 (ROC-AUC 0.852)
  • 肝毒性: 预测肝损伤风险
  • Ames致突变性: 预测基因突变风险

2. ADMET性质预测

  • 溶解度: 水溶性等级预测
  • 代谢稳定性: 半衰期预测
  • CYP450抑制: 药物相互作用风险

3. 虚拟筛选

  • 综合评分系统
  • Top N候选筛选
  • 分子结构可视化

使用方式

预测单个分子

import { predictMolecule } from './src/commands/predict';

const result = await predictMolecule('CC(C)Cc1ccc(cc1)C(C)C(=O)O');
console.log(result);
// {
//   smiles: 'CC(C)Cc1ccc(cc1)C(C)C(=O)O',
//   hERG: { risk: 'Low', probability: 0.05 },
//   hepatotoxicity: { risk: 'Low', probability: 0.10 },
//   ames: { risk: 'Low', probability: 0.05 },
//   overall: 'Safe'
// }

批量预测

import { batchPredict } from './src/commands/predict';

const results = await batchPredict([
  'CCO',
  'CC(C)O',
  'c1ccccc1'
]);

虚拟筛选

import { virtualScreen } from './src/commands/screen';

const topCandidates = await virtualScreen('molecules.csv', 10);
