In fiction
Notable examples include Lucy Whitmore in 50 First Dates, Jonathan Archer in the Star Trek: Enterprise episode "Twilight", Joseph Gordon-Levitt in The Lookout, Kaori Fujimiya in One Week Friends, Chihiro Shindou in Ef: A Fairy Tale of the Two, Christine Lucas in Before I Go to Sleep, Gus in Remember Sunday. Christopher Nolans psychological crime film Memento (2000) contains a distinguished depiction of anterograde amnesia, in that the memory-impaired protagonist Leonard Shelby is trying to identify and kill the man who raped and murdered his wife, and does so through a system of writing crucial details related to the search on his body and on the blank spaces of Polaroid photographs. Mental health experts have described Memento as one of the most accurate depictions of amnesia in film history, an accuracy that was enhanced by the films fragmented, non-linear structure that mimics the protagonists memory problems.Dory, the happy-go-lucky Regal Blue Tang from Finding Nemo (2003) and Finding Dory (2016), suffers from anterograde amnesia. While Dory forgets conversations within minutes of having them, she never quite forgets who she is, or the fact that she has short-term memory loss, and can therefore explain her bizarre behavior to those around her.Ghajini (2008), a Hindi language film of India based on Memento, in which the main protagonist Sanjay Singhania played by Amir Khan has short-term memory loss, this variant of amnesia. In the film he is behind Ghajini, the killer of his fiancée Kalpana.
Mechanism of action
Miltefosine primarily acts on Leishmania by affecting the speciess promastigote and amastigote stages. Miltefosine exerts its activity by interacting with lipids, inhibiting cytochrome c oxidase and causing apoptosis-like cell death. This may affect membrane integrity and mitochondrial function of the parasite. History
Cancer
While initially studied as a cancer medication, due to side effects it was never used for this purpose.Phospholipid group alkylphosphocholine were known since the early 1980s, particularly in terms of their binding affinity with cobra venom. In 1987 the phospholipids were found to be potent toxins on leukemic cell culture. Initial in vivo investigation on the antineoplastic activity showed positive result, but then only at high dosage and at high toxicity. At the same time in Germany, Hansjörg Eibl, at the Max Planck Institute for Biophysical Chemistry, and Clemens Unger, at the University of Göttingen, demonstrated that the antineoplastic activity of the phospholipid analogue miltefosine (at the time known as hexadecylphosphocholine) was indeed tumour-specific. It was highly effective against methylnitrosourea-induced mammary carcinoma, but less so on transplantable mammary carcinomas and autochthonous benzo(a)pyrene-induced sarcomas, and relatively inactive on Walker 256 carcinosarcoma and autochthonous acetoxymethylmethylnitrosamine-induced colonic tumors of rats. It was subsequently found that miltefosine was structurally unique among lipids having anticancer property in that it lacks the glycerol group, is highly selective on cell types and acts through different mechanism.
