Costunolide (Costus lactone) 是一种天然的倍半萜内酯，具有抗氧化、抗炎、抗过敏、骨重塑、神经保护、促进毛发生长、抗癌和抗糖尿病的特性，可诱导乳腺癌细胞周期阻滞和凋亡。

L-778123 hydrochloride 是一种FPTase 和GGPTase-I 双重抑制剂，IC50分别为2 nM 和 98 nM。

Lipiferolide is an inhibitor of farnesyl protein transferase(FPTase), it inhibits the FPTase activity in a dose-dependent manner, and shows cell growth inhibitory activity against several tumor cells, it possesses cytotoxic activity against KB cells. Liriodenine also has antiplasmodial activity.

Lonafarnib (Sch66336) 是一种可口服的 FPTase 抑制剂，作用于 H-ras、K-ras 和 N-ras，IC50分别为 1.9 nM、5.2 nM 和 2.8 nM。它具有抗肝炎三角洲病毒的活性。

L-778123 is an inhibitor of FPTase and GGPTase-I. The combination of L-778123 and radiotherapy at dose level 1 showed acceptable toxicity in patients with locally advanced pancreatic cancer.

XR3054 is a novel inhibitor of farnesyl protein transferase (FPTase). XR3054 inhibited the proliferation of the prostatic cancer cell lines LnCAP and PC3 and the colon carcinoma SW480 and HT1080 (IC50 values of 12.4, 12.2, 21.4 and 8.8 microM, respectively) but was relatively inactive when tested against a panel of breast carcinoma cell lines. The activity did not relate to the presence of mutant or wild-type ras in the cell lines tested. In conclusion XR3054 inhibits ras farnesylation, MAP kinase activation and anchorage-independent growth in NIH 3T3 transformed with v12 H-ras. Since the antiproliferative effect of the compound is not related to the ras phenotype, XR3054 may also have effects on other cell signaling mechanisms.

L-778123 is an inhibitor of FPTase and GGPTase-I, which was developed in part because it can completely inhibit Ki-Ras prenylation. The combination of L-778,123 and radiotherapy at dose level 1 showed acceptable toxicity in patients with locally advanced pancreatic cancer. Radiosensitization of a patient-derived pancreatic cancer cell line was observed.

(Rac)-Lonafarnib (Sch66336外消旋体) 作为Lonafarnib的外消旋体，属于一种口服有效的法尼基蛋白转移酶 (FPTase) 抑制剂，针对H-ras、K-ras及N-ras展现出杰出的抑制效能，其IC50值分别为1.9 nM、5.2 nM和2.8 nM。此外，Lonafarnib还显示出对抗肝炎三角洲病毒 (HDV) 的潜在活性。
