There is one exact (name or code) match for methylene blue

 
Methylene blue, also known as methylthioninium chloride, is a medication from WHO's list of essential medicines. Upon administration, methylene blue is converted to leukomethylene blue by erythrocyte methemoblobin reductase in the presence of NADPH. Leukomethylene blue than reduces methemoglobin to oxyhemoglobin, thus restoring oxygen carrying capacity of the blood. Methylene blue is also used as a dye for various diagnostic procedures, for treatment of ifosfamide toxicity and for in vitro staining. Historically, it was used as a photosensitizer for photodynamic therapy for topical treatment of dermatologic or mucocutaneous infections, as an antidote for cyanide poisoning, but these applications are no longer approved. Methylene blue is investigated in clinical trials for treatment of septic shock and Alzheimer's disease.

Taurolidine [bis(1,1-dioxoperhydro-1,2,4-thiadiazinyl-4)-methane (TRD)], a product derived from the aminosulfoacid taurin, was first described as an anti-bacterial substance. Taurolidine is a small dimeric molecule with molecular weight 284. It comprises the semiconditional amino acid taurine. Taurolidine was originally designed as a broad-spectrum antibiotic. Taurolidine has a broad antimicrobial spectrum of activity that is effective against aerobes and anaerobes, Gram-negative and Gram-posi-tive bacteria as well as yeasts and moulds in vitro. Taurolidine is also effective against methicillin-resistant and vancomycin-resistant bacteria (MRSA, VISA and VRE). It was mainly used in the treatment of patients with peritonis as well as antiendoxic agent in patients with systematic inflammatory response syndrome. It has been shown to be an effective bactericidal agent against both aerobic and anaerobic bacteria. It is currently licensed for intraperitoneal use in several European countries for the treatment of peritonitis. The compound appears to be nontoxic and has an excellent safety record since its initial introduction over 30 years ago. Taurolidine also possesses antiadherence properties and has been shown in vivo to reduce the extent and severity of postoperative peritoneal adhesions. It also possesses a strong anti-inflammatory action. This action appears, at least in part, to arise through its ability to inactivate endotoxin. Inflammation-induced tumor development is well described in the literature. Taurolidine’s anti-inflammatory and antiadherence properties prompted an investigation to examine whether it has a role in antitumor therapy. Taurolidine induces cancer cell death through a variety of mechanisms. It appears to act through enhancing apoptosis, inhibiting angiogenesis and tumor adherence, downregulating proinflammatory cytokine and endotoxin levels, and stimulating the immune system in response to surgically induced trauma. Taurolidine is currently in preclinical development for neuroblastoma. In February 23, 2018 the U.S. Food and Drug Administration (FDA) granted orphan drug designation to taurolidine for the treatment of neuroblastoma. Taurolidine is a key component in the Neutrolin®, a novel anti-infective solution for the reduction and prevention of catheter-related infections and thrombosis in patients requiring central venous cathers in end stage renal disease. Neutrolin contains a mix of Taurolidine, Citrate and Heparin. Neutrolin is designed to: 1) Aid in the prevention of Catheter-Related Bloodstream Infections (CRBIs) and 2) Prevent catheter dysfunction (due to blood clotting).

Ponesimod is an experimental drug for the treatment of multiple sclerosis (MS) graft-versus-host disease and psoriasis. It acts on certain types of white blood cells (lymphocytes) which are involved in the autoimmune attack on myelin seen in multiple sclerosis (MS). Ponesimod is an orally active, reversible, and selective sphingosine-1-phosphate receptor (S1PR1) modulator. The drug is in phase II clinical trial for the treatment of graft-versus-host disease. In addition, the phase III clinical trial comparing ponesimod to teriflunomide in relapsing-remitting MS is ongoing.
Nifurtimox is a nitrofuran derivative used as a primary agent in the treatment of American trypanosomiasis (Chagas' disease) caused by Trypanosoma cruzi, especially in the acute, early stage of the disease. The efficacy of nifurtimox in the treatment of chronic Chagas' disease varies from one country to another, possibly due to variation in the sensitivity of different strains of the organism. Nifurtimox has also been used to treat African trypanosomiasis (sleeping sickness) and is active in the second stage of the disease (central nervous system involvement). When nifurtimox is given on its own, about half of all patients will relapse, but the combination of melarsoprol with nifurtimox appears to be efficacious. Nifurtimox forms a nitro-anion radical metabolite that reacts with nucleic acids of the parasite causing significant break down of DNA. Nifurtimox undergoes reduction and creates oxygen radicals such as superoxide. These radicals are toxic to T. cruzi. Mammalian cells are protected by the presence of catalase, glutathione, peroxidases, and superoxide dismutase. Accumulation of hydrogen peroxide to cytotoxic levels results in parasite death. Side effects occur following chronic administration, particularly in elderly people. Major toxicities include immediate hypersensitivities such as anaphylaxis and delayed hypersensitivity reaction involving icterus and dermatitis. Central nervous system disturbances and peripheral neuropathy may also occur.
Brilliant Blue G is triphenylmethane dye that was developed for use in the textile industry but is now commonly used for staining proteins in analytical biochemistry. The Bradford assay is a standard, rapid dye-binding assay that uses Brilliant Blue G to quantify the amount of protein in a solution. Brilliant Blue G also acts as a selective inhibitor of the P2X purinoceptor channel P2X7 (IC50s = 10.1 and 265 nM for rat and human P2X7, respectively). In mice, it inhibits interleukin-1β expression and reduces neurological injury secondary to traumatic brain injury. Brilliant Blue G was used to prepare the protein reagent for the determination of protein content of the collagenase enzyme isolated from fish waste. It may be employed as a stain for the internal limiting membrane (ILM) for the macular hole (MH) and epiretinal membrane (ERM) surgery.
Fostamatinib is a pro-drug of a Syk inhibitor R406 initially developed by Rigel Pharmaceuticals, but then in-licensed by AstraZeneca. It reached phase III of clinical trials for such diseases as Rheumatoid Arthritis and Immune Thrombocytopenic Purpura, however, AstraZeneca decided not to proceed with regulatory filings and return the rights to the compound to Rigel Pharmaceuticals. In 2018 the drug was approved by the FDA for treatment of chronic immune thrombocytopenia. Fostamatinib is being developed for Autoimmune Hemolytic Anemia (phase II), graft versus host disease (phase I) and ovarian cancer (phase I).

Efinaconazole is triazole used as a 10% topical solution for the treatment of onychomycosis, a fungal infection of the nails. It was approved for use in Canada and the USA in 2014 and is marketed by Valeant Pharmaceuticals North America LLC under the name Jublia. Like other antifungal triazoles, efinaconazole inhibits the fungal cytochrome P450 enzyme lanosterol 14α demethylase (CYP51), thereby disrupting ergosterol synthesis and, consequently, membrane integrity and growth in fungi. CYP51 is evolutionarily conserved and, in mammals, mediates conversion of lanosterol to meiosis-activating sterols (MAS); MAS are intermediates in the biosynthesis of cholesterol and may have a signaling role in initiating meiosis and oocyte maturation. Azoles have higher affinity for fungal CYP51 compared to the mammalian enzyme and such selectivity contributes to the safety of this therapeutic class. Azoles have been reported to produce reproductive and developmental toxicity in both humans and laboratory animals. The mechanism is unknown but inhibition of mammalian CYP51 as well as other CYPs, e.g. CYP17, CYP19 and CYP26, have been postulated to play a role.
Nintedanib is a receptor tyrosine kinase inhibitor with potential antiangiogenic and antineoplastic activities. It is the only kinase inhibitor drug approved to treat idiopathic pulmonary fibrosis. that targets multiple receptor tyrosine kinases (RTKs) and non-receptor tyrosine kinases (nRTKs). Nintedanib inhibits the following RTKs: platelet-derived growth factor receptor (PDGFR) α and β, fibroblast growth factor receptor (FGFR) 1-3, vascular endothelial growth factor receptor (VEGFR) 1-3, and Fms-like tyrosine kinase-3 (FLT3). Among them, FGFR, PDGFR, and VEGFR have been implicated in IPF pathogenesis. Nintedanib binds competitively to the adenosine triphosphate (ATP) binding pocket of these receptors and blocks the intracellular signaling which is crucial for the proliferation, migration, and transformation of fibroblasts representing essential mechanisms of the IPF pathology.
TAK-536 (generic name: azilsartan) is an angiotensin II type 1 receptor blocker, discovered by Takeda and its mechanism of action is to lower blood pressure by inhibiting action of a vasopressor hormone Angiotensin II. Angiotensin II type 1 receptor antagonists have become an important drug class in the treatment of hypertension and heart failure. TAK-536 is in phase III clinical trial for treatment hypertension. This drug also known as active metabolite of the prodrug azilsartan medoxomil (also known as azilsartan kamedoxomil), but in some countries azilsartan rather than its prodrug is used for oral treatment.
