Thymopentin prepared in 5, 15, and 20% 2-hydroxypropyl-beta-cyclodextrin (HPCD) was able to inhibit guinea-pig ileum contraction stimulated by anatoxin-a (3 x 10(-6) M) after fourteen months of storage at room temperature. Thus, in contrast to the instability of thymopentin prepared without HPCD, the pharmacological activity was retained and could be stored in a ready-to-use solution for extended periods without refrigeration.
用5%、15%和20%的2-羟丙基-β-环糊精（HPCD）制备的胸腺五肽，在室温下储存14个月后，能够抑制由anatoxin-a（3×10⁻⁶ M）刺激引起的豚鼠回肠收缩。因此，与未添加HPCD制备的胸腺五肽的不稳定性相反，其药理活性得以保留，并且可以在无需冷藏的即用型溶液中长期储存。
