phase 下之 TI1(remove charges)、TI3(add charges)的部分則僅需 1 條軌跡即可。而 在 solution phase 下,不論是 TI1、TI2、TI3 都只需要在 production run 進行 600ps 即可得到收斂數值。

比較 TTA 與 STA 的部分,單就比較各自之 solution phase 或者是 complex phase 自由能,差異會較大,我們所探討的原因是在於電荷計算上使用到 particle mesh Ewald,Ewald summation 為龐雜的數學計算,在 TTA 與 STA 當中略有不同,因 而導致單獨就 solution phase 或者是 complex phase 之自由能差距較為的大。若將小 分子化合物當中所有原子電荷數值減小,即將電荷效應減小,則可發現單就自由

最後根據先前本實驗室所做出有 Ki 值之兩化合物相對自由能利用 RESP 計算 電荷情況下能夠得到僅僅與實際實驗值相差 1.1kcal/mol 之數值。因此可推論在相 同的結晶結構環境下,以先前作的為基準預測新化合物的誤差值也在此附近,所 以 CFO 相較於 82A 以能量觀點來說;是更為理想抑制 Erk 的分子。
