In A549 cells, motexafin gadolinium (50 µM; 22 h) causes dichlorofluorescein ether salt (DCFA) to oxidize [1]. When coupled with Zn (100 μM) and ascorbic acid (100 μM), motezafin gadolinium (100 μM; 4, 12 hours) promotes intracellular ROS generation and cell disinfection (24 hours) in Ramos cells [2]. Combining motezafin gadolinium (0.01-100 μM) with zinc (100 μM) and ascorbic acid (100 μM) in HF-1 cells lowers p53 protein expression in a cautious manner [2].

| Additional Infomation |
Motexafin gadolinium is a drug being investigated by Pharmacyclics for cancer treatment. It may increase the sensitivity of tumor cells to radiotherapy, improve tumor images on magnetic resonance imaging (MRI), and kill cancer cells. It belongs to the metalloporphyrin class of drugs. It is also known as gadolinium texaphyrin. Motexafin gadolinium is a synthetic metalloporphyrin with radiosensitizing and chemosensitizing properties. Due to the accelerated metabolic rate of tumor cells, motexafin gadolinium preferentially accumulates in tumor cells, generating reactive oxygen species (ROS) intracellularly, thereby lowering the apoptosis threshold of tumor cells in response to ionizing radiation and chemotherapy. (NCI04)
Drug Indications Studied for the treatment of brain cancer, other cancers/tumors (not specified), lung cancer, and non-Hodgkin's lymphoma. Mechanism of Action Motexafen gadolinium (Xcytrin) is Pharmacyclics' most advanced anticancer candidate, a small molecule drug with a novel mechanism of action. Due to the accelerated metabolic rate in cancer cells, Xcytrin selectively accumulates within them. Once inside the cell, Xcytrin induces apoptosis (programmed cell death) by disrupting redox-dependent pathways. Xcytrin inhibits thioredoxin reductase, a tumor growth promoter. This mechanism makes Xcytrin a promising treatment for a variety of cancers. Xcytrin is paramagnetic, allowing for detection via magnetic resonance imaging (MRI), enabling visualization of the drug within tumors. |

Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).
