A compound represented by the formula [I]: or a pharmacologically acceptable salt or ester thereof, wherein Ring A represents a five-membered aromatic heterocyclic group or the like fused with a non-aromatic ring group, which may be substituted, Ring B represents a phenyl group or the like which may be substituted, X1 represents a single bond or the like, R1 and R2 each represent a C1-6 alkyl group or the like, m represents an integer of 0 to 3, and n represents an integer of 0 to 2, is effective as a therapeutic agent for a disease caused by Aβ.

Novel 3‐alkoxymethyl/3‐phenyl indole‐2‐carboxamide derivatives were synthesized and evaluated for their anticancer activity. Most of the tested compounds showed moderate to excellent activity against the tested cell lines (MCF7 and HCT116). 3‐Phenyl substitution on indole with p‐piperidinyl phenethyl 24a and p‐dimethylamino phenethyl 24c exhibited anticancer activity against MCF7 with IC50 of 0.13 and 0.14 μm, respectively. Further mechanistic study of the most active compounds through their action on cell cycle showed disturbance in cell cycle progression and cell cycle arrest. For future development of this series of compounds, pharmacophore study was conducted which indicated that the enhancement of the activity could be achieved through the addition of acceptor or donating groups to the already‐present indole nucleus.

From a group of pyrrolo[2,3-d]pyrimidine compounds that have been screened against influenza virus, one derivative, 4-(3-piperidinyl benzylamino)-2-methyl-7H-pyrrolo[2,3-d]pyrimidine (9), has shown promising activity against both the A and B strains. The compound had activity comparable to amantadine, but was inactive when given orally. 4-(Substitutedphenyl ethylamino)-2-methyl-7H-pyrrolo[2,3-d]pyrimidines showed no improved activity.
