Methylcobalamin is a form of vitamin B12, where a methyl group replaces cyanide. It features an octahedral cobalt(III) center and can be obtained as bright red crystals. Notable for containing metal-alkyl bonds, it is physiologically equivalent to vitamin B12. Methylcobalamin is used to treat conditions from vitamin B12 deficiency, including pernicious anemia, peripheral neuropathy, and diabetic neuropathy, and as an initial treatment for amyotrophic lateral sclerosis.

Enzo Life Sciences Protoporphyrin IX (free acid) (300mg). CAS: 553-12-8
Protoporphyrin IX free acid, as distinct from its zinc salt (which inhibits heme oxygenase), activates soluble guanylyl cyclase (sGC) by binding directly to the enzyme. A useful reagent in cases where the use of nitric oxide (NO) or nitric oxide donors is undesirable. Alternative name: 8,13-Divinyl-3,7,12,17-tetramethyl-21H,23H-porphine-2,18-dipropionic acid. Purity: ≥95% (HPLC). Solubility: Dissolve initially in 0.1M base (Tris base or NaOH), then add water miscible organic solvent (EtOH (10mg/ml), MeOH, DMSO (10mg/ml), DMF) until solution is 50/50 base/solvent. When a clear solution is obtained, it can be diluted into an aqueous medium and titrated or buffered to any pH>7. Use immediately. Long Term Storage: -20°C.

Protoporphyrin IX is a final intermediate in the heme biosynthetic pathway, which acts as a radiation sensitizer enhancing ROS generation even in a hypoxic state and inducing DNA damage. It also functions as a photosensitizer, undergoing photobleaching through direct degradation by light irradiation. It accumulates following 5-aminolevulinic acid (5-ALA) administration in rat tumor cells. When activated by red fluorescence at a peak wavelength of 405 nm, Protoporphyrin IX selectively improves basal cell carcinoma. It shows promise as a sonodynamic and photodynamic agent for various cancers, including bladder cancer and nodular basal cell carcinoma.
- Acts as a radiation sensitizer enhancing ROS generation.
- Induces DNA damage.
- Acts as a photo sensitizer.
- Promising for research of sonodynamic and photodynamic agents for a wide range of cancers.
