培美曲塞 (LY231514) 二钠肿瘤是一个新型的经典抗叶酸药物家族，其抗活性可能是由于其多谷氨酸启动子同时协同抑制多种必需叶酸酶的需求。最著名的酶 FPGS 底物之一是培美曲塞 (LY231514)，其 Km 为 1.6 μM，Vmax/Km 为 621。LY231514 的选择性和抗肿瘤功效可能由其聚谷氨酸和聚谷氨酸辅助剂决定。虽然TS仅被LY23l5l4抑制（在重组小鼠中Ki=340 nM），但LY23l5l4的谷氨酸性很强。最有效的叶酸 TS 之一是 LY231514，其含量高出 100 倍 (Ki=3.4 nM) [1]。

从统计学上来说，PC61加培美曲塞组的小鼠比其他组的存活时间更长。根据生存分析，用 PC61 联合培美曲塞治疗的小鼠比单独用 PC61、大鼠 IgG 加培美曲塞或不治疗的小鼠有显着更高的生存率 [2]。

Effects During Pregnancy and Lactation
◉ Summary of Use during Lactation Most sources consider breastfeeding to be contraindicated during maternal high-dose antineoplastic drug therapy. The manufacturer recommends that mothers should not to breastfeed during treatment with pemetrexed and for one week after the last dose. Chemotherapy may adversely affect the normal microbiome and chemical makeup of breastmilk.[1] Women who receive chemotherapy during pregnancy are more likely to have difficulty nursing their infant.[2] ◉ Effects in Breastfed Infants Relevant published information was not found as of the revision date. ◉ Effects on Lactation and Breastmilk Relevant published information was not found as of the revision date. 28170295 |

Pemetrexed(2-) is a dicarboxylic acid dianion obtained by deprotonation of both carboxy groups of pemetrexed. It is a dicarboxylic acid dianion and a N-acyl-L-alpha-amino acid anion. It is a conjugate base of a pemetrexed.
A guanine-derived ANTINEOPLASTIC AGENT that functions as a NUCLEIC ACID SYNTHESIS INHIBITOR through its binding to, and inhibition of, THYMIDYLATE SYNTHASE. Drug Indication Malignant pleural mesotheliomaAlimta in combination with cisplatin is indicated for the treatment of chemotherapy-naïve patients with unresectable malignant pleural mesothelioma. Non-small-cell lung cancer Alimta in combination with cisplatin is indicated for the first-line treatment of patients with locally advanced or metastatic non-small-cell lung cancer other than predominantly squamous cell histology. Alimta is indicated as monotherapy for the maintenance treatment of locally advanced or metastatic non-small-cell lung cancer other than predominantly squamous cell histology in patients whose disease has not progressed immediately following platinum-based chemotherapy. Alimta is indicated as monotherapy for the second line treatment of patients with locally advanced or metastatic non-small-cell lung cancer other than predominantly squamous cell histology. |

| 溶解度 (体内实验) |
配方 1 中的溶解度: 33.33 mg/mL (64.54 mM) in PBS (这些助溶剂从左到右依次添加，逐一添加), 澄清溶液; 超声助溶。
请根据您的实验动物和给药方式选择适当的溶解配方/方案： 1、请先配制澄清的储备液(如：用DMSO配置50 或 100 mg/mL母液(储备液)); 2、取适量母液，按从左到右的顺序依次添加助溶剂，澄清后再加入下一助溶剂。以 下列配方为例说明 (注意此配方只用于说明，并不一定代表此产品 的实际溶解配方): 10% DMSO → 40% PEG300 → 5% Tween-80 → 45% ddH2O (或 saline); 假设最终工作液的体积为 1 mL, 浓度为5 mg/mL: 取 100 μL 50 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中，混合均匀/澄清；向上述体系中加入50 μL Tween-80，混合均匀/澄清；然后继续加入450 μL ddH2O (或 saline)定容至 1 mL； 3、溶剂前显示的百分比是指该溶剂在最终溶液/工作液中的体积所占比例; 4、 如产品在配制过程中出现沉淀/析出，可通过加热(≤50℃)或超声的方式助溶; 5、为保证最佳实验结果，工作液请现配现用！ 6、如不确定怎么将母液配置成体内动物实验的工作液，请查看说明书或联系我们; 7、 以上所有助溶剂都可在 Invivochem.cn网站购买。 |
| 制备储备液 | 1 mg | 5 mg | 10 mg | |
| 1 mM | 1.9364 mL | 9.6820 mL | 19.3641 mL | |
| 5 mM | 0.3873 mL | 1.9364 mL | 3.8728 mL | |
| 10 mM | 0.1936 mL | 0.9682 mL | 1.9364 mL |
1、根据实验需要选择合适的溶剂配制储备液 (母液)：对于大多数产品，InvivoChem推荐用DMSO配置母液 (比如：5、10、20mM或者10、20、50 mg/mL浓度），个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;
2、如果您找不到您想要的溶解度信息，或者很难将产品溶解在溶液中，请联系我们;
3、建议使用下列计算器进行相关计算（摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等）;
4、母液配好之后，将其分装到常规用量，并储存在-20°C或-80°C，尽量减少反复冻融循环。
计算结果:
工作液浓度： mg/mL；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL)。如该浓度超过该批次药物DMSO溶解度，请首先与我们联系。
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL ddH2O，混匀澄清。
(1) 请确保溶液澄清之后，再加入下一种溶剂 (助溶剂) 。可利用涡旋、超声或水浴加热等方法助溶；
(2) 一定要按顺序加入溶剂 (助溶剂) 。
