The interactions of gefitinib (Iressa) in EGFR are hydrogen bonding and van der Waals forces through quinazoline and aniline rings. However the morpholino group of gefitinib is poorly ordered due to its weak electron density. A series of novel piperazino analogues of gefitinib where morpholino group substituted with various piperazino groups were designed and synthesized. Most of them indicated significant

The invention relates to novel compounds, in particular novel O-substituted phospholipids that are useful for the in vitro and in vivo delivery of drugs as well as nucleic acids into cells. The invention also relates to pharmaceutical compositions and supramolecular complexes comprising said compounds and the use of these compounds in therapeutic treatment, in particular in gene therapy.

Compounds related to acetazolamide and to its N-methyl derivatives, of the formulae: ##STR1## wherein Y is one of the following groups: ##STR2## R.sub.1 being a straight or branched alkylene or arylalkylene, or a phenylene, and the processes for their preparation; the compounds so obtained are inhibitors of carbonic anhydrase like acetazolamide but, in addition, they are well absorbed topically so that they can be used as drugs for treating glaucoma.
Abstract Homologous series of crystallisable C8-C22 even-numbered alkane oligomers with either maleate or itaconate monoesters end-groups were synthesized. Their total phase change enthalpy (ΔHtpce) and entropy (ΔStpce) on melting, determined by DSC, show a linear dependence with the number of carbons of the alkyl chain. A comparison was performed with corresponding succinate derivatives. The influence

EGFR mutation (T790M) and cancerous stemness have shown drug resistances in human non-small-cell lung cancer (NSCLC), thus development of novel drugs in overcoming drug resistances in the NSCLC therapy is highly desired. SP101 is a novel gefitinib derivative, which can bind the ATP-binding pocket of EGFR to inhibit its EGFR kinase activity. SP101 can reduce the drug resistances of EGFR mutation (T790M) and cancerous stemness in NSCLC. SP101 induced cancer cell death and apoptosis in the gefitinib-resistant EGFR mutation (T790M) H1975 cells. SP101 inhibited phosphorylated EGFR and its downstream Survivin proteins but conversely induced Caspase 3 activation for apoptosis induction. Moreover, SP101 could decrease Oct4 protein level and reduce Survivin proteins but conversely elicited active Caspase 3 in the xenograft human H1975 lung tumors in nude mice.
