English scientist Robert Robinson was also working on the synthesis of physostigmine, but surprisingly Julian, a relatively unknown scientist at the time, was the successful one.In 1934, while working at St Alfeges Hospital in London, Dr Mary Walker discovered that a subcutaneous injection of physostigmine could temporarily reverse the muscle weakness found in patients with myasthenia gravis. She had noted that the symptoms and signs of myasthenia were similar to those found in curare poisoning, and physostigmine was used as an antidote to curare poisoning at that time. Her article explaining the first case of myasthenia gravis being successfully treated with physostigmine was published in The Lancet in June 1934. See also

In 2004, 3M obtained FDA approval to market imiquimod as a treatment for superficial basal cell carcinoma.In 2006, 3M sold its pharmaceutical business in the Americas to Graceway Pharmaceuticals, its European pharmaceutical business to Meda AB, and its pharmaceutical business in other territories to two private equity firms.Graceway declared bankruptcy in 2011, after the expiration of the patents on imiquimod, and its assets, including the rights to imiquimod branding and approvals in the Americas, were purchased by Medicis Pharmaceutical.Imiquimod 5% was approved for medical use in the European Union in September 1998. Imiquimod 3.75% was approved for medical use in the European Union in August 2012.As of 2015, imiquimod is generic and is available worldwide under many brands. Research
One randomized double-blind Phase III clinical study found clearance of genital warts (an FDA-approved indication) improved from 9% with placebo to 24.9% with 3.75% imiquimod cream applied for up to eight weeks.Imiquimod has been tested for treatment of molluscum contagiosum. Two large randomized controlled trials, however, found no evidence of effectiveness of imiquimod in treating children with molluscum contagiosum, and concerning adverse effects were also noted. These disprove earlier anecdotal claims and smaller, less reliable studies.Imiquimod has also been tested for treatment of vulvar intraepithelial neoplasia, vaginal intraepithelial neoplasia, common warts (a 2012 Cochrane review found no randomized controlled trials), plantar warts, warts in people with suppressed immune systems, flat warts on face and neck, and warts under and around fingernails and toenails.
