摘要:
The present invention provides new chemical compounds, N-(4-phenyl-2-thiazolyl)carbamate derivatives, a process for preparing the same and pharmaceutical compositions containing the carbamate derivatives. More particularly, the present invention provides N-(4-phenyl-2-thiazolyl)carbamate derivatives which have immuno-modulating activity and are thus effective against immunodiseases such as chronic rheumatoid arthritis and also useful against viral diseases or for the immunotherapy of cancers with low toxicity.
摘要:
Disclosed are 2-thiazol derivatives having the general formula ##STR1## where R.sub.1 and R.sub.2 independently represent lower alkyl radicals having 1 to 4 carbon atoms and X represents a lower alkyl radical, a lower alkoxy radical, a lower alkoxycarbonyl radical, a halogenoalkoxy radical, a radical of the formula ##STR2## or a radical of the formula ##STR3## Also disclosed are a process for preparing the derivatives and pharmaceutical compositions having immunomodulatory activity which comprise the derivatives as the active ingredient.
摘要:
The present invention provides new thiazole compounds possessing immuno-modulating activity, i.e. thiazole compounds of the general formula (1): ##STR1## wherein R.sub.1 stands for a hydrogen or halogen atom or a lower alkyl, lower alkoxy, substituted or unsubstituted phenoxy, nitro or cyano group, R.sub.2 for a hydrogen atom or a lower alkyl or lower alkylthio group, and R for an .alpha.-halogenoalkyl group or the grouping: ##STR2## a process for preparing same and pharmaceutical compositions containing the thiazole compounds.More particularly, the present invention provides new thiazole compounds of the above general formula (1) which have immuno-modulating activity and are thus effective against immunodiseases such as chronic rheumatoid arthritis and also useful against viral diseases or for the immunotherapy of cancers, but show weak toxicity and are thus extremely desirous as medicines, a process for the preparation of the thiazole compounds and pharmaceutical compositions containing the thiazole compounds.
摘要:
The present invention provides thiazolyl derivatives as new chemical substance represented by the general formula: ##STR1## wherein R.sup.1 stands for a lower alkyl group or a substituted or unsubstituted phenyl group, R.sup.2 for a hydrogen atom, a lower alkyl, lower alkoxy or lower alkylthio group, and R.sup.3 for a pyridyl or iso-oxazolyl group or a grouping of the general formula: ##STR2## processes for preparing same and pharmaceutical compositions containing the thiazolyl derivatives. More particularly, the present invention provides new thiazolyl derivatives which possess immuno-modulating activity and are thus therapeutically effective against immunodiseases such as chronic rheumatoid arthritis and also useful against viral diseases or for the immunotherapy of cancers and possess properties desirous as medicines with a slight toxicity, processes for preparing same and pharmaceutical compositions containing the new substance.

摘要:
The present invention relates to a piperazine compound represented by the following general formula (I): ##STR1## wherein X stands for a hydrogen atom or a phenyl group, R.sup.1 stands for a hydrogen atom or an alkyl group, and R.sup.2 stands for a hydrogen atom or an alkyl group.These compounds are valuable as immunopotentiators, such as for the treatment of chronic rheumatoid arthritis and other diseases accompanied by reduction or abnormal change of the immune function.
摘要:
An antenna apparatus (60) is provided which is used in a recorder and/or player to write and read data to and from a contactless IC card (1). The antenna apparatus (60) includes a loop coil (61) to radiate an electromagnetic field for magnetic coupling with a loop coil (4) at the IC card (1) to send and receive data to and from the IC card (1), and a magnetic sheet (62) disposed to face the main side of the loop coil (61), opposite to the main side facing the IC card (1). The magnetic sheet (62) has the specific permeability μ′ and product Ms·t of saturation magnetization Ms and thickness t thereof set in accordance with a necessary range of communications with the contactless IC card (1).
