MedKoo CAT#: 555960

CAS#: 104162-48-3 (Z-isomer chloride)

Description: DOTMA is one of the first cationic lipid used for gene transfection. DOTMA is an effective transfection agent in vitro and in vivo. DOTMA carries a positive charge on the surface of liposomes which condenses anionic nucleic acids and promotes efficient interactions between the cell membrane and the liposome. Note: DOTMA is the Z-isomer (or Cis-isomer) chloride salt, which CAS# is 104162-48-3. While DOTMA E-isomer (trans-isomer) chloride salt has CAS#104872-42-6. Some vendors confused each other.

More Info:

Biological target: DOTMA, as a tetra-methylated DOTA analogue, is a cationic lipid and can be used as a non-viral vector for gene therapy.
In vitro activity: In particular, the Ln(3+) chelates of DOTMA exhibit a marked preference for the monocapped twisted square antiprismatic coordination isomer which imparts more rapid water exchange kinetics on the chelates; τ(M)(298) was determined to be 85 ns for GdDOTMA. Reference: Inorg Chem. 2011 Sep 5;50(17):7955-65. https://pubmed.ncbi.nlm.nih.gov/21819052/
In vivo activity: The present study aimed to evaluate the incorporation of the natural lipid lycopene into niosome formulations based on cationic lipid DOTMA and polysorbate 60 non-ionic surfactant to analyze the potential application of this novel formulation to deliver genetic material into the rat retina. Both subretinal and intravitreal administrations to the rat retina showed that nioplexes were able to transfect efficiently the outer segments of the retina, which offer reasonable hope for the treatment of many inherited retinal diseases by a safe non-viral vector formulation after the less invasive intravitreal administration.
