Description
当给猪施用猪生长激素(PST)以例如提高其生长速率、料-肉转化率、瘦肉率和/或产奶量时,生长激素可以导致胃溃疡,严重时可导致死亡,参见Swith和Kasson,J.Anim.Sci.68:4109-16(1990)和69:571-77(1991)。这些作者指出生长激素引起的这种溃疡的机理还不清楚。由于多种常规使用的抗溃疡药对缓解施用了生长激素的猪的溃疡不起作用,使得对这一机理更难于理解。
例如,组胺H2受体拮抗剂如Tagamet
甲氰咪胍(Smithkline Beecham)、Zantac
糠硝烯二胺(Glaxo)、Pepcid
famotidine(Merck)和Axid
nizatidine(Lilly)广泛地用于治疗人的胃溃疡。但是,现已发现当给予经PST处理而患溃疡的猪每天三次每天150mg的糠硝烯二胺注射7天时,组胺H2受体拮抗剂糠硝烯二胺对缓解其溃疡几乎无效。
通常用于溃疡的治疗药物还有细胞保护剂,例如含有Al(OH)3和Mg(OH)2的药物,如carafate
硫糖铝(Marion Merrell Dow)和De-Nol
胶体次柠檬酸铋(Gist-Brocades)。这些药物能与蛋白质性质的渗出物(白蛋白)在溃疡部位形成一种复合物并因此形成一层能阻止氢离子渗透到胃上皮组织的膜屏障。但是,当给PST处理的58-67kg的猪喂饲每3kg细磨粉制成的颗粒料中加入了1或4gm硫糖铝的饲料时,发现其对缓解胃溃疡无效或无肯定性的疗效,而施用500mg/天De-Nol同样无效。
各种E-型前列腺素能够缓解人的溃疡,这一点已有明确的说明。但是,当以每天两次经口管饲法服用总量分别为400或800μg/天的米索前列腺醇(misoprostol)时,这种合成的前列腺素E甲酯,Cytotec
米索前列腺醇(Searle)对缓解由PST处理引起的猪溃疡只有很弱的作用。而自由基清除剂能够缓解未用PST处理的猪的胃溃疡。例如,维生素U对饲料引起的猪的溃疡有疗效。Tamas等,Oesophagogastric Ulcer in Swine and Vitamin U,Ⅲ-Ⅳ,34Acta.Veterinaria Hungarica 81-100(1986)。但是,当饲料中含有800ppm维生素U时,发现其对PST处理引起的猪的胃溃疡没有显著疗效。其它的自由基清除剂,例如维生素E(100IU/kg加上0.25ppm硒),和其它可能的饲料中的溃疡缓解剂,例如麸子(5%),Santoquin
饲料防腐剂(Monsanto)(0.75gm/天),燕麦壳(9%)和半胱氨酸(800ppm)同样对PST处理引起的猪的胃溃疡无效或统计学意义上无效。
现已发现其它已知的胃溃疡的治疗剂对PST处理的猪也无效或统计学意义上无效。例如发现维生素K3形式的维生素K(6mg/天),一种与凝血时间有关的药物,和苜宿(饲料中占9%;维生素E和K中更高)均无效,而降低胃排空速度的饲料添加剂,例如动物脂(6%)和Stafac
抗菌的生长促进剂(0.011%)也无效或统计学意义上无效。
可以相信的是从商业角度以通常可预想的比率施用PST,由PST加重溃疡而致死的猪的比例很少大于百分之几,通常小于百分之一。然而,为了改善猪的工业价值和提供高质量的(瘦肉)猪肉制品,最大可能地实现生长激素的最大效力,本发明提供了用于缓解施用了PST引起的猪的溃疡的方法和产品。实现本发明目的及其它方面的具体实施和应用通过下列描述是显而易见的。
本发明提供了一种对施用了外源的生长激素的猪缓解溃疡并降低伴随的死亡率的方法,包括给猪施用缓解这种溃疡的有效量的选自杂环基烷基(亚硫酰基或硫基)苯并咪唑和[苯并咪唑基(亚硫酰基或硫基)烷基]苯胺的苯并咪唑化合物以改善猪的健康状况和/或降低其死亡率。
本发明还提供了用于实施本发明方法的产品,包含猪生长激素和选自杂环基烷基(亚硫酰基或硫基)苯并咪唑和[苯并咪唑基(亚硫酰基或硫基)烷基]苯胺的苯并咪唑化合物,所述产品适合于将生长激素和苯并咪唑化合物同时注射以达到提高猪的生长速度,饲料效率,瘦肉率和产奶有效量的生长激素和可缓解猪胃溃疡有效量的苯并咪唑化合物延时释放到猪的循环系统中的作用。
杂环基烷基(亚硫酰基或硫基)苯并咪唑用于缓解未施用外源的生长激素的哺乳动物的胃溃疡是公知的。参见美国专利4,045,563和4,045,564(Berntsson等;1977,8,30公开);4,182,766(Krasso等,1980,1,8公开);4,255,431(Junggren等;1981,3,10公开),4,472,409(Senn-Bilfinger;1984,9,18公开);4,628,098(Nohara等;1986,12,9公开);4,758,579(Kohl等;1988,7,19公开);4,873,337(Sih等;1989,10,10公开),5,039,806(Bradstram等,1991,8,13公开);以及5,045,321(Makino等;1991,9,3公开),这些文献在此只作为参考,但是,已经发现广泛使用的此类化合物中的一个,5-甲氧基-2-[(4-甲氧基-3,5-二甲基-2-吡啶基)甲基亚硫酰基]苯并咪唑(Prilosec
甲氧磺唑(omeprazole;Merck)对缓解由胆管结扎诱导的猪的胃溃疡无效。Stapleton等,Sucralfate in the Prevention of Porcine Experimental Peptic Ulceration,86(suppl.6A)Amer.J.Med.21-22(1989)。各种吡啶基烷基硫基苯并咪唑,它们的口服或非肠道施用的药物以及它们的生物(抗炎性)活性在1971,6,3公开的英国专利1,234,058中已经阐述。
[苯并咪唑基亚硫酰基烷基]苯胺用于缓解未施用外源的生长激素的哺乳动物胃溃疡也是公知的。例如见Adelstein等,Substituted2-[(2-Benzimidazoly sulfinyl)methyl]anilines as Potential Inhibitors of H+/K+ATPase,31 J.Med.Chem.1215-20(1988)和1986,12,10公开的欧洲专利申请号204,215,这些文献在此只作为参考。
本发明适用于任何施用了生长激素的猪,这些猪可以包括施用了生长激素促其产奶的牝猪。但是,本发明最常用于生长的猪(例如成猪),它们可以是阉猪,小母猪或未阉的公猪。这些猪的体重一般在约20-约150kg之间。
用于本发明的生长激素包括任何对猪具有生长激素样活性的化合物。这些化合物包括与自生的猪生长激素的作用等同的化合物或具有与其相似的生物活性的其它化合物。这些实例公开于美国专利4,861,868(Krivi;1989,8,29公开)和5,104,806(Souza;1992,4,14公开),欧洲专利申请1990,2,28公开的355,460(Cady等),1984,6,20公开的欧洲专利申请号111,389(Seeburg等),1984,4,4公开的欧洲专利申请号104,920(Movva等)和1991,6,5公开的欧洲专利申请号429,788(Wang等),这些文献在此只作为参考。生长因素释放因子或其它生长激素促泌素,是通过刺激另外的内源生长激素的释放来模仿给予外源的生长激素,它们的施用应该被认为是与本发明的目的相同。
PST可以通过每日注射或其它非肠道方法施用,较理想地是通过注射或植入一个释放系统将PST在至少约1周,较优选地是至少约3周内释放到猪循环系统中的方法施用。PST的释放期较理想地是约6周或更长,其可以以任何比率(固定的或可变的)以及以任何可提高猪的生长速度、料-肉转化率(“饲料效率”)、瘦肉率和产奶的有效量施用。平均比率通常为至少约1mg/天,优选地是至少约2mg/天。出于经济上的原因和其它原因,日剂量通常是不大于约20mg/天,较普遍地是不大于约10mg/天,而最理想地是不大于5mg/天。
用于本发明的苯并咪唑化合物可以是任何对缓解猪胃溃疡,特别是对猪胃溃疡特别敏感的食管部分的溃疡有效的杂环基烷基(亚硫酰基或硫基)苯并咪唑。典型地是可有效抑制猪胃上皮细胞中H+/K+三磷酸腺苷酶活性的苯并咪唑。
如上述已有技术中所示,此类苯并咪唑化合物中杂环基部分可以是吡啶基,咪唑基,咪唑啉基,苯并咪唑基,噻唑基,噻唑啉基,喹啉基或哌啶基,其中每个可以未被进一步取代或具有1,2或3个环上取代基(相同或不相同),只要取代基并非不可接受地影响用于本发明的苯并咪唑化合物的作用。这些取代基(相同或不相同的)可以选自氯、溴、氟、碘、烷基和氟化烷基,其中每个烷基可以是含有1,2,3或4个(优选地是1个)碳原子的直链或支链烷基。
同样如上述已有技术中所示,与杂环基部分和亚硫酰基或硫基部分的硫原子相连的烷基可以是含有1,2,3或4个(优选地是1个)碳原子的直链或支链烷基。在此用作证的是下列苯并咪唑:
吡甲硫唑-2-[2-吡啶基甲基亚硫酰基]苯并咪唑;
吡甲硫唑的硫基类似物*-2-[2-吡啶基甲硫基]苯并咪唑;
甲氧磺唑-5-甲氧基-2-[(4-甲氧基-3,5-二甲基-2-吡啶基)甲基亚硫酰基]苯并咪唑;和
lansoprazole-2-[[3-甲基-4-(2,2,2-三氟乙氧基)-2-吡啶基]甲基亚硫酰基]苯并咪唑。
*有时指作吡甲硫唑硫化物或还原的吡甲硫唑。
用于本发明最优选的是2-[2-吡啶基甲基(亚硫酰基或硫基]苯并咪唑,特别是包括吡甲硫唑,其硫基类似物,以及5-甲氧基-2-[(4-甲氧基-3,5-二甲基-2-吡啶基)甲基亚硫酰基]苯并咪唑,包括甲氧磺唑。通常,特别是以某些施用方法例如粒剂注射法,吡甲硫唑可以提供良好的结果,按照由注射的粒剂延时并稳定释放的方法,其硫基类似物可以提供更好的结果。此类苯并咪唑的制备方法是公知的;有些已在专利中和在已有技术描述过程中引述的专利申请中公开。本发明有用的各种2-[2-吡啶基甲基硫基]苯并咪唑,它们的制备以及将它们转变成本发明有用的相应的2-[2-吡啶基甲基亚硫酰基]苯并咪唑的方法已在1988,8,3公开的欧洲专利申请302,720和/或上述英国专利1,234,058中公开,这些文献在此只作为参考。许多这些化合物相似的有用的结构变体以及它们的制备方法对本专业技术人员是显而易见的。
另外,用于本发明的苯并咪唑化合物可以是任何可有效缓解猪胃溃疡,特别是食管部分溃疡的[苯并咪唑基(亚硫酰基或硫基烷基]苯胺。典型地是这些苯并咪唑可有效抑制酸分泌酶H+/K+三磷酸腺苷酶的活性。这些苯并咪唑中较优选的是2-[(2-苯并咪唑基亚硫酰基或硫基甲基]苯胺,其可未进一步被取代或具有选自氯、溴、氟、碘,每个都含有1,2,3或4个碳原子的烷基和氟化烷基的取代基(相同或不同),只要这种取代基对用于本发明的苯并咪唑化合物的作用无不可接受的影响。此类苯并咪唑化合物的具体例证是:
2-[(2-苯并咪唑基硫基甲基]-N-甲基苯胺;
2-[(2-苯并咪唑基亚硫酰基)甲基]-N-甲基苯胺;
2-[(2-苯并咪唑基硫基甲基]-4-甲基苯胺;
和
2-[(2-苯并咪唑基亚硫酰基)甲基]-4-甲基苯胺。
苯并咪唑化合物可以口服,例如在饲料和水中,或者非肠道施用,例如与生长激素一起或分别注射。较理想地是将生长激素和苯并咪唑一齐或同时施用,即注射或植入一个在延时期内(优选地是基本相当的)它们通常可以分别同时释放到猪循环系统中的剂量。此延时释放可以通过一个含有苯并咪唑化合物流动剂的植入的渗透泵来完成,或者可以通过在期望的时期内可足以提供所需日剂量的通过紧密干燥的微粒状苯并咪唑制成的注射的粒剂来完成。苯并咪唑化合物的施用比率和施用量可以是能明显缓解(即预防或降低了严重程度)猪胃溃疡,特别是对食管部分溃疡有效的比率和量。这些将依赖于所用具体的苯并咪唑化合物的效力,品种的溃疡敏感度或在猪的治疗和保养环境里猪的其它特性。尽管施用比率和施用量可以各不相同,但其最普遍地是至少约1mg/天(优选地是至少5mg/天),通常不大于约50mg/天(优选地是不大于25mg/天)。
下列具体实施例只做说明而对本发明的范围无任何限制作用。
实施例1-4
对几种苯并咪唑化合物用作施用了PST的猪胃溃疡缓解剂进行试验。将体重为约90-100kg的杂交的60头阉猪随机地分成6组,每组10头:
1组 -对照组(即不施用PST也不施用苯并咪唑)。
2-6组 -每日注射大剂量(20mg/天)的PST注射6天以加速溃疡发展,研究溃疡抑制作用。
3组(实施例1) -通过管饲法另外口服40mg/天甲氧磺唑。
4组(实施例2) -通过管饲法每日两次每次20mg而另外口服40mg/天甲氧磺唑。
5组(实施例3) -每日两次每次20mg另外注射40mg/天吡甲硫唑。
6组(实施例4) -每日两次每次200mg另外注射400mg/天吡甲硫唑。
使用美国专利4,861,868中公开的具有在天然PST序列上连有N-丙氨酰的PST。对所有的猪随意地喂细磨料、颗粒料和再次磨细料(18%蛋白质并补充了0.25%赖氨酸)。6天后,由猪身上取出胃并依据下述系统对溃疡进行评价。
溃疡的评价
距与胃连接点5cm处切断食管和十二指肠,分离出胃。将胃由幽门沿胃大弯直至食管开口5cm处切开。将胃排空,内表面轻轻擦净而不擦伤食管部分,将胃展开使其内表面朝上,随后,通过评价损伤的规模和深度确定所出现的溃疡的严重程度。将环绕胃食管部分基本上所有地方的损伤指定为全部损伤,如果实际上还剩有部分上皮组织,则损伤被指定为部分损伤。溃疡的深度可指定为轻度、中度或重度。轻度溃疡是指上皮层表面只轻微有点变红,糜烂深度为约0.25mm的溃疡为中度,而结果是在溃疡区完全没有了上皮层的深度糜料(例如几个毫米)为重度。当溃疡规模(面积)和深度确定后,按下列数字表示法来评价溃疡的严重程度:
部分和轻度-1 全部和中度-7
全部和轻度-3 部分和重度-8
部分和中度-5 全部和重度-10
1-6组的溃疡评价结果如表Ⅰ所示:

第5天时有一头猪死亡,原因未确定,但没有溃疡产生。
结果显示甲氧磺唑可很有效地缓解PST处理引起的猪胃溃疡,而吡甲硫唑在更大程度上对缓解PST处理引起的猪胃溃疡有效。
对比实施例A和B
在实施例1-4的研究中,对另外的两组,每组10头猪,每头以相同的方法和相同的用量(20mg/天)于同样的6天内分别施用150mg/天糠硝烯二胺(每日3次每次注射50mg)和800μg/天米索前列腺醇(每日2次每次管饲法口服400μg)。这两组的溃疡评价结果分别为4.90和6.67,由此说明此两种治疗对缓解PST处理的胃溃疡基本无效。
实施例5-7
如实施例1-4,对作为施用了PST引起的猪胃溃疡缓解剂的吡甲硫唑进行试验,将40头体重约90-100kg杂交的阉猪随机地分成下述4组,每组10头。
1组 -每日注射大剂量(20mg/天)的PST注射6天以加速溃疡发展,研究溃疡抑制作用。
2组(实施例5) -每日两次每次20mg,即注射40mg/天吡甲硫唑。
3组(实施例6) -每日两次每次5mg,即注射10mg/天吡甲硫唑。
4组(实施例7) -通过植入的Alzet泵稳定输注10mg/天吡甲硫唑。
所有的猪随意地喂予细磨料、颗粒料和再次磨细的饲料(18%蛋白质并补充了0.25%赖氨酸)。7天后,按实施例1-4中所述系统对所有存活的猪的胃进行溃疡评价,结果如表Ⅱ所示。

以几种不同施用方法给予吡甲硫唑或其硫基类似物试验其缓解每日注射实施例1-4中使用的同种PST引起的猪胃溃疡的作用。将80头体重约90-100kg杂交的阉猪随机地分成下述8组,每组10头:
1组 -对照组(既不施用PST也不施用苯并咪唑)。
2组 -以20mg/天PST注射28天。
3组(实施例8) -以20mg/天PST和40mg吡甲硫唑/天注射28天。
4组(实施例9) -20mgPST/注射6天,然后20mg PST/天和40mg吡甲硫唑/天注射22天。
5组(实施例10) -20mg PST/注射6天,然后3mg PST/天和10mg吡甲硫唑/天注射22天。
6组 -20mg PST/注射6天,然后3mg PST/天注射22天。
7组 -既不施用PST也不施用苯并咪唑22天,然后20mg PST/天注射6天
8组 -既不施用PST也不施用苯并咪唑22天;然后20mg PST/天和40mg/天的2-[2-吡啶基甲硫基]苯并咪唑注射6天。
所有的猪都随意地喂予细磨料,颗粒料和再次磨细的饲料(18%蛋白质并补充了0.25%赖氨酸)。29天后,根据实施例1-4中所述系统,对所有猪(除备注的)的胃进行溃疡评价,结果如表Ⅲ所示。
