Description
諸如跳蚤、虱、蠅、蚊子、壁蝨及蟎等外寄生蟲以及諸如胃腸道線蟲、吸蟲及絲蟲等內寄生蟲對人類及同樣動物有害。該等寄生蟲藉由減緩體重增加、使獸皮、羊毛及肉品質變差並在一些情形中導致死亡而嚴重影響馴養動物行業之生產力。外寄生蟲及內寄生蟲亦部分的係疾病及不適在食物及伴侶動物中之傳播的原因。特定而言,已知外寄生蟲攜帶並傳播各種微生物病原體(包括細菌、病毒及原蟲寄生蟲),其中許多對人類、其他溫血哺乳動物及鳥係致病的。與外寄生蟲相關之疾病包括(但不限於)瘧疾、淋巴性-及血液媒介絲蟲病、砂眼、錐蟲病、利什曼體病(Leishmaniasis)、落磯山斑點熱(Rocky Mountain Spotted Fever)、萊姆病(Lyme Disease)、焦蟲病及由(例如)沙門桿菌屬(Salmonella)、大腸桿菌(E.coli)及曲狀桿菌屬(Campylobacter)所致之食物媒介疾病。
寄生蟲感染之醫學重要性已促使研發能夠控制該等之試劑。例如,常常遇到之控制寄生蟲感染之方法通常著重於殺昆蟲劑之使用,殺昆蟲劑經常由於以下原因中之一或多者而不成功或令人不滿意:(1)所有者或施用者順從性不足(需要頻繁投與);(2)動物對殺蟲劑產品或投與方式之行為或生理不耐受性;(3)對試劑有抵抗力之外寄生蟲之出現;及(4)對環境之負面影響及/或毒性。
具體而言,壁蝨寄生於野外以及馴養動物及人類中,且
已知或懷疑係包括細菌、病毒及原蟲寄生蟲之病原體之傳播的原因。目前,認為壁蝨係世界上僅次於蚊子的人類疾病之病媒,但認為其係北美洲(North America)最重要的病原體病媒。由於需要伴隨處理中間宿主以及環境儲庫,故有效消除壁蝨感染很困難且經常不切實際。目前,壁蝨控制係藉由害蟲整合管理來實現,其中在適當考慮不同控制方法之環境效應之情況下,該等不同控制方法適應於一個區域或抵抗一個壁蝨物種。
儘管使用殺昆蟲劑及殺蟲劑已係有益的,但需要替代或改良之化合物、調配物及方法。期望化合物、調配物及方法將不僅提供替代治療,且亦將克服目前方法之一或多個限制。該等限制包括毒性及動物及使用者/所有者兩者之安全性、有限效力(例如效能及持續時間)及抵抗力問題。亦影響殺昆蟲劑及殺蟲劑之有益用途係投與障礙,其包括投與模式及再次投與。例如,期望減少投與頻率同時維持效力,此乃因過度及重複治療動物經常不方便及/或難以進行。
本發明涵蓋殺寄生蟲化合物、方法及調配物,其用於在動物及植物中及其上使用且提供對抗殺寄生蟲感染、特定而言殺體外寄生蟲感染之替代選擇。另外,本發明之某些態樣克服在使用目前殺昆蟲劑及殺蟲劑中、特定而言在有效長期安全控制寄生蟲中之至少一些限制。

可針對動物中蠕蟲感染之一或多個生活期評價化合物以量測活體內驅蠕蟲劑活性。可基於毫克/公斤體重以單一劑量投與、隨後進行劑量滴定來評價化合物,以測定最低有效點劑量。例如,在齧齒類驅蠕蟲劑模型中,使用化合物向經圓蟲線蟲(Strongylid nematode)之一或多個物種(例如撚轉胃蟲(Haemonchus contortus)及/或蛇形毛樣圓蟲(Trichostrongylus colubriformis))傳染之成年蒙古沙鼠(Mongolian gerbil)(長爪沙漠鼠(Meriones unguiculates))投
藥,經由經口胃管灌食法投與。對沙鼠進行屍體剖檢,並量測胃腸道蟲負荷並與未經處理之經傳染對照沙鼠比較以測定驅蠕蟲劑活性程度。可在較高級物種(例如狗、貓、綿羊、牛)中實施類似測試,藉此將經處理動物中之線蟲負荷與未經處理之經傳染動物中之負荷比較以量測驅蠕蟲劑活性之效能及持續時間。
活體外幼蟲浸漬微量分析(Larval Immersion Microassay,LIM)
可如White等人,J.Med.Entomol.41:1034-1042(2004)中所闡述實施幼蟲浸漬微量分析。簡言之,將實驗測試物質(test article)調配於二甲亞碸(DMSO)中以製備濃度為10 mM之儲備溶液。隨後使用96孔微孔板,將10 mM樣品之等份試樣稀釋於含有1%乙醇及0.2% Triton X-100之基於水之溶液中,以在0.1 ml之體積中獲得期望濃度(通常0.3 mM或更低)之實驗測試物質(最小值n=3個重複/化合物或濃度)。將大約30-50條孤星壁蝨幼蟲(Lone star tick larvae)(美洲壁蝨(Amblyomma americanum))浸沒於每一含有實驗測試物質之孔中。30分鐘浸漬時期之後,使用寬口移液管吸頭移取存於0.05 ml之流體中之幼蟲,將其分配至頂部用塑膠透析夾密封之市售紙質組織生檢袋中,倒置並空氣乾燥60分鐘。然後在大約27℃及>90%相對濕度下培育含有幼蟲之袋。24小時之後,打開袋,計數活的及死的幼蟲,並如下計算幼蟲死亡率百分數:效力%=(#死的幼蟲)/(#活的幼蟲)×100。
在此分析中在300微莫耳下測試時,以下實例呈現效力且在80%效力之位準下:32、36、37、38、39、40、41、42、43、44、45、46、47、48、49、50、51、52、53、54、55、56、57、58、59、60、61、62、63、64、65、66、67、68、69、70、71、72、74、75、76、77、78、79、80、81、82、83、84、85、86、87b、94、95、96、230、231、232、233、236、237、240、241、243、244、245、246、247及249。
活體內齧齒類殺蟎劑測試(RAT)
可使用Gutierrez等人,J.Med.Entomol.43(3):526-532(2006)中所闡述之分析之修改版評價實驗測試物質。藉由使用諸如狗矩頭壁蝨(Dermacentor variabilis)壁蝨等不同壁蝨物種(此文獻闡述美洲壁蝨)修改此分析。另外,此文獻闡述局部投與,但可使用經口投與。簡言之,在聚乙二醇-300、丙二醇及水之溶液中將實驗測試物質調配至期望濃度(通常1-25 mg/ml),其取決於溶解度及期望點劑量。將壁蝨圍阻單元(由嬰兒用奶嘴、通氣螺旋蓋頂部及強化橡膠墊圈組成)附接至成年斯普拉-道來氏(Sprague-Dawley)大鼠之背部。附接圍阻單元後,將大約10條未餵食之稚蟲期美國狗壁蝨(狗矩頭壁蝨)置於每一圍阻單元內部。感染大約24小時之後,經由經口胃管灌食法向大鼠投與測試物質調配物。陰性對照大鼠僅接受聚乙二醇-300、丙二醇及水。視化合物可利用性而定,每處理群組利用最少三(3)隻且最多五(5)隻大鼠。處理四十八(48)個小時後,
移除圍阻單元並計數活的及死的壁蝨。使用自然對數轉換加1(Ln計數+1)轉換活的壁蝨計數;向每一計數加1用於調整為0之計數。經由群組平均轉換計數之逆轉換及減去1獲得幾何平均(GM)群組壁蝨計數。使用未經處理對照群組與接受實驗測試物質之群組比較用於計算效力%(活的壁蝨計數之減少%)。藉由將在經處理大鼠上所觀察到之活的壁蝨之幾何平均(GM)數量與在陰性對照大鼠上所計數之活的壁蝨之GM數量比較並使用下式來計算處理之效力:
在此分析中以不超過25 mpk之劑量測試時,以下實例呈現50%效力:32、36、38、39、41、42、43、45、46、47、49、50、51、52、53、54、55、56、57、58、59、61、87b、95、96、234、235、240、241、243、244、245、246、247及249。
以上分析中之活性證明本發明化合物對於控制外寄生蟲或內寄生蟲感染係有用的。
