The most promising compound (3) has shown activity in rat and mouse collagen (II)-induced arthritis models (ED50 = 2 and 31 mg/kg, respectively) and has shown a shorter half-life in man when compared with leflunomide.

Long‐range electronic substituenteffects were targeted using the substituent dependence of δC(C═N), and specific cross‐interactions were explored extendedly. A wide set of N‐(4‐X–benzylidene)‐4‐(4‐Y–styryl) anilines, p‐X–C6H4CH═NC6H4CH═CHC6H4–p‐Y (X = NMe2, OMe, Me, H, Cl, F, CN, or NO2; Y = NMe2, OMe, Me, H, Cl, or CN) were prepared for this study, and their 13C NMR chemicalshifts δC(C═N) of C═N bonds

Polymer modified adducts are prepared by (A) reacting (1) an epoxy resin having an average of more than one vicinal epoxide group with (2) a compound containing an average of two or more hydrogen atoms reactive with an epoxide group; and (B) partially vinylizing reacting the product from step (A); and (C) polymerizing the partially vinylized product from step (B) with (3) a polymerizable ethylenically unsaturated monomer; with the proviso that at least one of the components (1), (2) or (3) contain one or more mesogenic or rodlike moieties. These adducts are useful as epoxy resin curing agents.
