Cytotoxic effect of some 1, 4-dihydropyridine derivatives containing nitroimidazole moiety.

Iranian journal of pharmaceutical research : IJPR, 2011
The 1,4-dihydropyridine (DHP) derivatives are a known class of calcium channel blockers. Some derivatives of DHP showed significant cytotoxicity. It was shown that this effect may not be the result of interaction with Ca(2+) channels. In this study, we performed an investigation about the intrinsic cytotoxicity of some derivatives of DHP containing ...

One-Pot Synthesis of 1, 4-Dihydropyridines in PEG Under Catalyst-Free Conditions [PDF]

Advances in Engineering Research, 2015
A simple, inexpensive, and efficient one-pot synthesis of 1,4-dihydropyridine via Hantzsch reaction was achieved in good to excellent yields under catalyst free conditions by using PEG400 as solvent. In this reaction, PEG-400 was used as the solvent, which has such advantages: absolutely nontoxic, inexpensive, thermally stable, recoverable and easy to ...

Additive‐Manufactured, Multifunctional Bioreactor Technology for Dynamic Culture of 3D Bioprinted Tissue Models

Advanced Materials Technologies, EarlyView.
We introduce an additively manufactured bioreactor with a perfusion flow system and integrated temperature and pH sensors for skeletal muscle tissue biofabrication. The bioreactor's performance was evaluated by assessing the viability, spreading of the myoblast cells in a printed scaffold, and contraction of the isolated murine musculi interossei ...
