Estramustine is an antineoplastic agent indicated in the palliative treatment of patients with metastatic and/or progressive carcinoma of the prostate. Estramustine is a combination of estradiol with nitrogen mustard. In vivo, the nitrogen-mustard moiety becomes active and participates in alkylation of DNA or other cellular components. This causes DNA damage in rapidly dividing cancerous cells leading to cell death and ideally, tumor shrinkage. Also, due to the drugs estrogen component, it can bind more selectively to active estrogen receptors. Used for the palliative treatment of patients with metastatic and/or progressive carcinoma of the prostate.
Phosphoric acid, also known as orthophosphoric acid, is used in dentistry and orthodontics to clean and roughen the surfaces of teeth where dental appliances or fillings will be placed. In addition, this acid is a part of product ProcalAmine, which is indicated for peripheral administration in adults to preserve body protein and improve nitrogen balance in well-nourished, mildly catabolic patients who require short-term parenteral nutrition. In combination with dextrose (glucose) and levulose (fructose), phosphoric acid relieves nausea due to upset stomach from intestinal flu, stomach flu, and food or drink indiscretions. In addition, homeopathic product, Brain power contains also phosphoric acid and this product is used to temporarily relieve symptoms of general physical weakness and listlessness, including: fatigue; sore muscles & joints; dry skin; absence of sexual desire; occasional sleeplessness.

Synthetic glycerophosphates have been known for many years and have been prepared in several ways. The acid may exist in two isomeric forms, alpha and beta. The L-a-acid is the naturally occurring form; the b-acid, present in hydrolyzates of lecithins from natural sources, arises from migration of the phosphoryl group from the a-carbon atom. Dehydrogenation of L-glycerol 3-phosphate produces Dihydroxyacetone phosphate and is part of the entry of glycerol (sourced from triglycerides) into the glycolytic pathway.

Mannose 6-phosphate (M6P) has type-I integral membrane receptors. M6P-receptors bind and transport M6P-enzymes to lysosomes, but it can also modulate the activity of a variety of extracellular M6P-glycoproteins (i.e., latent TGFbeta precursor, urokinase-type plasminogen activator receptor, Granzyme B, growth factors, Herpes virus). M6P has been demonstrated to reduce active TGF-β1 expression on cultured tendon fibroblasts and improved range of movement in a rabbit flexor tendon injury model. Studies of M6P in relation to skin scarring demonstrate improvement in scar cosmesis and accelerated return of normal dermal architecture. Juvidex, a formulation of M6P, inhibits the activation of TGF-beta1 and TGF-beta2, which are present at high levels in adult wounds that scar. On the other hands, M6P in a 600 mM hypertonic solution (Adaprev) potentially acts via a physical, non-chemical, hyperosmotic effect.

Targets:


Fosbretabulin (Combretastatin A4 phosphate, CA4P) is the lead compound of a relatively new class of agents termed vascular disrupting agents that target existing tumor blood vessels. Rapid tumor blood flow shutdown has been demonstrated in preclinical models and patients by various techniques such as dynamic contrast-enhanced MRI, perfusion computed tomography and PET scans following CA4P infusion. CA4P typically induces rapid tumor necrosis in the center of the tumor and leaves a rim of viable cells in the periphery. In oncology, CA4P does not appear to be that active by itself, but may be more efficacious when combined with chemotherapy, antiangiogenic therapy and radiation therapy. Combretastatin was initially isolated from the root bark of the South African Bush willow Combretum caffrum in 1982 by Pettit and colleagues at the Arizona State University (AZ, USA). Combretastatin A4 phosphate binds avidly to tubulin at the colchicine-binding site to inhibit microtubule assembly and destabilize the cytoskeleton. CA4P is a tubulin-binding agent that binds at or near the colchicine binding site of β-tubulin (Kd = 0.40 uM), inhibits tubulin assembly with IC50 of 2.4 uM. Fosbretabulin has orphan drug status in the EU and the US for the treatment of ATC (Anaplastic Thyroid Cancer). Later the development of this drug was discontinued.
