Miltefosine is an alkylphosphocholine that shows broad-spectrum in vitro antifungalactivities and limited in vivo efficacy in mouse models of cryptococcosis. To further explore the potential of this class of compounds for the treatment of systemic mycoses, nine analogs (3a−3i) were synthesized by modifying the choline structural moiety and the alkyl chain length of miltefosine. In vitro testing of
Miltefosine 是一种烷基磷酸胆碱,在体外具有广谱抗真菌活性,在隐球菌病小鼠模型中的体内疗效有限。为了进一步探索此类化合物治疗全身性真菌病的潜力,通过修饰米替福新的胆碱结构部分和烷基链长度,合成了九种类似物 ( 3a - 3i )。这些化合物对机会性真菌病原体白色念珠菌、光滑念珠菌、克柔念珠菌、烟曲霉和新型隐球菌的体外测试表明,N-苄基-N、N-二甲基-2-[(十六烷氧基)羟基膦基]氧基}乙胺内盐(3a ),N,N-二甲基-N- (4-硝基苄基)-2-[(十六烷氧基)羟基膦基]氧基}乙胺内盐( 3d ),和N- (4-甲氧基苄基) -N,N-二甲基-与 MIC 为 2.5-3.3 μg/mL 的米替福新相比,2-[(十六烷氧基)羟基膦基]氧基}乙胺内盐 ( 3e ) 对所有测试病原体的最小抑制浓度 (MIC) 为 2.5-5.0 μg/mL。化合物3a对三种类似于米替福新的哺

Additive products are provided for use in the washing of textiles comprising a mixture of an organic peroxy bleach precursor, a cationic surfactant and an alkoxylated nonionic surfactant of HLB 8 -17 in water releasable combination with a non-particulate substrate, the additive products being adapted for addition to conventional inorganic persalt- containing detergent liquors to enhance the removel of bleachable and greasy stains.
A detergent additive product intended to enhance removal of oxidisable and oily stains from textiles comprising a substantially water impermeable container enclosing an organic matrix consisting of 30-85% by weight of a normally solid water soluble ethoxylated nonionic compound and 15-70% by weight of an organic peroxybleach precursor, optionally with 1-75% by weight of the matrix of other water soluble detergent components especially cationic surfactants, organic chelating agents and soil suspending agents. The particulate product has a maximum dimension in the range 1-4 mm, a penetrometer indentation of less than 1 mm, a wicking value (resistance to nonionic bleeding) <10 and should disperse in aqueous inorganic persalt-containing detergent solution to release at least 50% of the theoretically available bleach within 8 minutes. In a preferred granular form, the product is coated with 1-30%. by weight of the matrix, of a powder coating which may be organic or inorganic.
Laundry additive products having improved machine compatibility containing specific amino-silanes. A preferred execution of the technology is a combination of a flexible substrate and the amino-silane. The claimed additives provide enhanced machine protection especially in relation to enamel coated surfaces.
