Mechlorethamine

According to the NCI the hydrochloride salt of mechlorethamine, is a nitrogen mustard and an analogue of sulfur mustard, with antineoplastic and immunosuppressive activities. Mechlorethamine is metabolized to an unstable, highly reactive ethyleniminium intemediate that alkylates DNA, particularly the 7 nitrogen of guanine residues, resulting in DNA base pair mismatching, DNA interstrand crosslinking, the inhibition of DNA repair and synthesis, cell-cycle arrest, and apoptosis.

Indikationen/Anwendungsmöglichkeiten gemäss Chemocare.com:
As part of combination regimens in treatment of Hodgkin's disease, non-Hodgkin's lymphoma. 
As palliative chemotherapy in lung and breast cancers.
As a lotion to skin lesions of mycosis fungoides (cutaneous T-cell lymphoma).

Megestrol

According to the NCI website Mimicking the action of progesterone, megestrol binds to and activates nuclear progesterone receptors (PRs) in the reproductive system and pituitary.

IIndikationen/Anwendungsmöglichkeiten gemäss folgendem Link (Medien Plus):
Megestrol tablets are used to relieve the symptoms and reduce the suffering caused by advanced breast cancer and advanced endometrial cancer (cancer that begins in the lining of the uterus). Megestrol suspension is used to treat loss of appetite, malnutrition, and severe weight loss in patients with acquired immunodeficiency syndrome (AIDS). Megestrol should not be used to prevent loss of appetite and severe weight loss in patients who have not yet developed this condition. Megestrol is a man-made version of the human hormone progesterone. It treats breast cancer and endometrial cancer by affecting female hormones involved in cancer growth. It increases weight gain by increasing appetite.

MEK 162

According to the NCI website the MEK inhibitor MEK162 isan orally available inhibitor of mitogen-activated protein kinase kinases 1 and 2 (MEK1/2) with potential antineoplastic activity. MEK inhibitor MEK162, noncompetitive with ATP, binds to and inhibits the activity of MEK1/2. Inhibition of MEK1/2 prevents the activation of MEK1/2-dependent effector proteins and transcription factors, which may result in the inhibition of growth factor-mediated cell signaling. This may eventually lead to an inhibition of tumor cell proliferation and an inhibition in production of various inflammatory cytokines including interleukin-1, -6 and tumor necrosis factor. MEK1 and MEK2 are dual-specificity threonine/tyrosine kinases that play key roles in the activation of the RAS/RAF/MEK/ERK pathway and are often upregulated in a variety of tumor cell types.

Antimetaboliten
Methotrexate

According to the NCI methotrexate is an antimetabolite and antifolate agent with antineoplastic and immunosuppressant activities. Methotrexate binds to and inhibits the enzyme dihydrofolate reductase, resulting in inhibition of purine nucleotide and thymidylate synthesis and, subsequently, inhibition of DNA and RNA syntheses. Methotrexate also exhibits potent immunosuppressant activity although the mechanism(s) of actions is unclear.

Indikationen/Anwendungsmöglichkeiten gemäss Arzneimittel-Kompendium der Schweiz®:

Behandlung hämatologischer Neoplasien wie akute lymphatische und myeloische Leukämie und Non-Hodgkin-Lymphom sowie solider Tumoren wie Mammakarzinom, Bronchialkarzinom, maligne Kopf- und Halstumoren, Osteosarkom, Chorionkarzinom und andere trophoblastische Tumoren, Blasenkarzinom.
Behandlung von Autoimmunerkrankungen wie z.B. rheumatoide Arthritis.
Behandlung schwerer Fälle unkontrollierbarer Psoriasis, welche gegenüber konventioneller Therapie resistent sind.

Zytostatikum

Midostaurin
According to the NCI website Midostaurin is a  synthetic indolocarbazole multikinase inhibitor with potential antiangiogenic and antineoplastic activities. Midostaurin inhibits protein kinase C alpha (PKCalpha), vascular endothelial growth factor receptor 2 (VEGFR2), c-kit, platelet-derived growth factor receptor (PDGFR) and FMS-like tyrosine kinase 3 (FLT3) tyrosine kinases, which may result in disruption of the cell cycle, inhibition of proliferation, apoptosis, and inhibition of angiogenesis in susceptible tumors.
 
 
Mitomycin

According to the NCI mitomycin C is a methylazirinopyrroloindoledione antineoplastic antibiotic isolated from the bacterium Streptomyces caespitosus and other Streptomyces bacterial species. Bioreduced mitomycin C generates oxygen radicals, alkylates DNA, and produces interstrand DNA cross-links, thereby inhibiting DNA synthesis. Preferentially toxic to hypoxic cells, mitomycin C also inhibits RNA and protein synthesis at high concentrations.

Indikationen/Anwendungsmöglichkeiten gemäss Medlineplus Druginfo:
This medication is used to treat adenocarcinoma of the stomach and pancreas.
