“…Further elucidation of the mechanisms underlying the therapeutic activity of GS and other drugs that have been or are successfully used to treat pemphigus may shed light on the pharmacologic mechanisms mediating pemphigus IgG^induced acantholysis. Nonsteroidal treatments of pemphigus reported to date include the following drugs (in chronological order): quinine and strychnine (reviewed in Kartamyshev, 1949), organic arsenic compounds (Oppenheim, 1927), suramin (also known as germanin or nephuride) (Veiel, 1931), vitamin D (Ludy and DeValin, 1932), methotrexate (Lever and Goldberg, 1969), azathioprine (Wol¡ and Schreiner, 1969), cyclophosophamide (Krain et al, 1972), gold (Penneys et al, 1973), dapsone (Haim and Friedman-Birnbaum, 1978), heparin (Mashkilleyson, 1985), cyclosporine (Balda and Rosenzweig, 1986), quercetin and doxycyline (Grando, 1988), aprotinin and e-aminocaproic acid (Grando, 1992), nicotinamide and tetracycline (Cha⁄ns et al, 1993), minocycline (Sawai et al, 1995), p-aminomethylbenzoic acid (Dobrev et al, 1996), mycophenolate mofetil (Enk and Knop, 1997), and tranilast (Miyamoto and Takahashi, 1997). Surprisingly, a single mechanism of action common for GS and many of the above listed nonsteroid drugs is cholinergic activity ( Table 2).…”
