Abstract: The present invention relates to a method of inhibiting tumor metastasis in an aminal by administering to an animal in need of such treatment an acrylaminoalkylpryridineamides represented by the formula ##STR1## wherein: R.sub.1 and R.sub.2 are the same or different members of the group consisting of halo, phenyl, substituted phenyl and a ##STR2## group wherein n, m and p are independently an integer of from 1 to 8 provided n+m+p is equal to or less than 10; x is thio or sulfinyl; Alk.sub.1 is straight or branched chain lower alkylene of 1 to 6 carbon atoms, R.sub.3 is hydrogen or lower alkyl, Alk.sub.2 is straight or branched chain alkylene of 1 to 4 carbon atoms; R.sub.4 is selected from the group consisting of hydrogen, halo, hydroxy, lower alkyl and lower alkoxy; or a pharmaceutically acceptable salt thereof, in an amount effective to inhibit tumor metastasis.

Abstract: A method of inhibiting tumor metastasis in an animal without treating the tumor cells by administering to said animal a metastasis inhibiting effective amount of a heterocyclic amide represented by the formula: ##STR1## wherein: R.sub.1 and R.sub.2 are the same or different members of the group consisting of halo, phenyl, substituted phenyl and a ##STR2## group wherein q, r and t are independently an integer of from 1 to 8 provided that q+r+t is equal to or less than 10; Y is thio or sulfinyl; alk is straight or branched chain lower alkylene, and R.sub.3 is a heterocyclic amine represented by the formula: ##STR3## wherein R.sub.4 is selected from the group consisting of hydrogen, lower alkyl, phenyl, substituted phenyl, benzyl, or substituted benzyl; p is 0 to 2; or a pharmaceutically acceptable salt thereof.

Abstract: A relatively lightweight insulating enclosure for placement over an attic structure such as a disappearing stairway or an attic fan, to reduce unwanted heat transfer through the structure when closed. The insulating enclosure comprises a number of box segments made of a lightweight insulating material such as foamed polystyrene, connected together with overlapping joints. Expansion members are optionally included to enlarge the width of the assembled enclosure.
