Organogel investigations as a floating oral system with depot property

Al-Mustansiriyah Journal of Pharmaceutical Sciences, 2022
In this work we investigate span 40, span 60 and SA as a gelators and olive oil (OO) as apolar liquid phase to discover the ability of organogel formed to be floating in acidic media and gain a unique gastroretentive dosage form.

Organogel delivery vehicles for the stabilization of organolithium reagents

Nature Chemistry, 2023
Organolithium reagents are a vital tool in modern organic chemistry, enabling the synthesis of carbon–carbon bonds. However, due to their high reactivity, low temperatures, inert atmospheres and strictly dried solvents are usually necessary for their use.

Towards racemizable chiral organogelators [PDF]

Beilstein Journal of Organic Chemistry, 2010
A chiral organogelator has been synthesized that can be racemized and self-assembled in apolar solvents whilst at higher concentrations organogels are formed. Field emission scanning and transmission electron microscopy revealed the formation of bundle fibrils that are able to gelate the solvent. 1H NMR studies showed hydrogen-bond interactions between
