Opis ogólny
(Hydroxypropyl)methylcellulose (HPMC) is a water-soluble polymer derived from cellulose. This polysaccharide forms colloids when dissolved in water. HPMC is a hydrocolloid produced artificially from natural substances. It consists of 28-30% methoxyl content and 7-12% of hydroxypropoxyl content.
Zastosowanie
(Hydroxypropyl)methyl cellulose (HPMC) has been used:
- as a viscosity modifier in the preparation of printable ink
- as a viscosifier in the preparation of hydroxyapatite (HAP) suspension
- in the preparation of HPMC gels and composite gels
Thickener for aqueous and non-aqueous systems, clear films with grease resistance, binders, lubricants, steric stabilizer and water retention aid.
Działania biochem./fizjol.
(Hydroxypropyl)methylcelluloses (HPMCs) act as suspension aids, surfactants, lubricants, protective colloids, and emulsifiers. Additionally, solutions of these polymers show thermal gelation properties. They are generally used as binders, thickeners, film formers, and water retention agents. HPMC also elicits surface-active properties.
Cechy i korzyści
Dissolves in water, undergoes reversible gelation upon heating, non-ionic, does not complex with ionic species and is surface active and enzyme resistant. Solutions are pseudoplastic.

The homeobox transcription factor PROX1 is induced by high Wnt/β-catenin activity in intestinal adenomas and colorectal cancer, where it promotes tumor progression. Here we report that in LGR5+ colorectal cancer cells, PROX1 suppresses the Notch pathway, which is essential for

Many tumour cells show dependence on exogenous serine and dietary serine and glycine starvation can inhibit the growth of these cancers and extend survival in mice. However, numerous mechanisms promote resistance to this therapeutic approach, including enhanced expression of the de

The nitro-chloromethylbenzindoline prodrug SN29428 has been rationally designed to target tumour hypoxia. SN29428 is metabolised to a DNA minor groove alkylator via oxygen-sensitive reductive activation initiated by unknown one-electron reductases. The present study sought to identify reductases capable of activating
