生物活性
Enzastaurin (LY317615)是一种有效的PKCβ选择性抑制剂，IC50为6 nM，比对PKCα， PKCγ和PKCε的作用强6到20倍。Enzastaurin阻断U87MG恶性胶质瘤细胞，PC-3前列腺癌细胞 ，及HCT116结肠癌细胞的增殖。当Enzastaurin浓度低于1 μM时则可能对HCT116和U87MG细胞有温和的诱导。Enzastaurin阻断许多细胞系如K-562, MOLT-4, HOP-92, 和PC-3细胞系的增殖。

| 细胞系 | PC-3 prostate cancer, HCT116 colon cancer, and U87MG glioblastoma cell lines |
| 方法 | Proliferation assays. Proliferation was assessed for all cell lines over a 6-day time course in media supplemented with 1% FBS (7 days total). Briefly, 1,000 cells were plated per well in a 96-well plate and changed to fresh media (1% FBS) with or without enzastaurin on days 1 and 4. On day 7, the media were removed and 100 μL propidium iodide (PI) solution (10 μg/mL in D-PBS) were added to each well. An initial reading for PI staining (excitation at 500 nmol/L, absorbance at 615 nmol/L) was done using the WallacVictor plate reader following a 30-minute incubation to determine the nonviable cell fraction. The plate was then frozen at –80 °C for 2 hours, thawed, and reread. The proliferative index was scored by subtracting the prefreeze data (nonviable cells) from the postfreeze data (all cells). |

不同实验动物依据体表面积的等效剂量转换表（数据来源于FDA指南）
| 小鼠 | 大鼠 | 兔 | 豚鼠 | 仓鼠 | 狗 |
| 重量 (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
| 体表面积 (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
| Km系数 | 3 | 6 | 12 | 8 | 5 | 20 |
| 动物 A (mg/kg) = 动物 B (mg/kg) × | 动物 B的Km系数 |
| 动物 A的Km系数 |
例如，依据体表面积折算法，将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量，需要将20 mg/kg 乘以小鼠的Km系数（3），再除以大鼠的Km系数（6），得到化合物用于大鼠的等效剂量为10 mg/kg。
