Neuromuscular blocking agents (NMBAs) are widely used in surgery to achieve skeleton muscles relaxation under light anesthesia status. In this work, we synthesized a series of 3,16-bisquaternary ammonium steroidal NMBAs. Among them, three compounds exhibited higher in vitro activities than the commenced drug rocuronium. In addition, structure-activity relationship was unveiled. We found that the intact acetylcholine-like moiety in D-ring was not necessary for maintaining activity but both the acetyl group and the quaternary nitrogen were very essential.
神经肌肉阻滞剂（NMBAs）在手术中被广泛应用，以在浅麻醉状态下实现骨骼肌松弛。在本研究中，我们合成了一系列3,16-双季铵甾体NMBAs。其中，三种化合物表现出比起始药物罗库溴铵更高的体外活性。此外，还揭示了构效关系。我们发现D环中完整的乙酰胆碱样部分对于维持活性并非必需，但乙酰基和季铵氮两者都非常重要。
