Disclosed is an adamantane derivative which enables to obtain a cured product which is excellent in optical characteristics such as transparency and light resistance, long-term heat resistance, and electrical characteristics such as dielectric constant. Also disclosed are a resin composition containing such an adamantane derivative, and a sealing agent for electronic circuits and an optoelectronic member respectively using those. Specifically disclosed are an adamantane derivative represented by the general formula (I) below, a resin composition containing such an adamantane derivative, a sealing agent for electronic circuits and an optoelectronic member respectively using such a resin composition, and an adhesive of those. (I) In the general formula (I), Z represents a group selected from the groups represented by the general formula (II) or (III) below (wherein R

Four dimeric and four monomeric lipophilic iminosugars were synthesized and subsequently evaluated on their inhibitory potential towards mammalian glucosylceramide synthase, glucocerebrosidase, β-glucosidase 2, sucrase and lysosomal α-glucosidase. Compared to their monomeric counterparts the dimeric inhibitors showed decreased inhibition of glucosylceramide synthase and generally a comparable inhibitory
