    摘要： Compositions free from mineral oil and used for freeing jammed drill pipes in drilling operations, and processes for using such compositions are disclosed. The compositions comprise a mixture of:(a) one or more fatty acid alkyl esters corresponding to the following general formula ##STR1## in which R.sup.1 is a linear C.sub.7 -C.sub.23 alkyl, alkenyl or alkadienyl radical andR.sup.2 is a linear or branched C.sub.1 -C.sub.8 alkyl or hydroxyalkylene radical,(b) one or more thickeners such as organophilic bentonites, and(c) one or more emulsifiers.Preferred emulsifiers include a mixture of an aminoamide or a polyamine and a fatty acid or calcium salt thereof. The composition may contain other conventional additives and is adapted to be formulated in the field by blending with water and/or weighting agents to achieve the proper thickness and density for use as a well spotting fluid.

    摘要： The invention provides methods of making and using compounds of the formula: or a pharmaceutically acceptable salt thereof; wherein n is an integer between 1 and 2 inclusively; m is an integer between 0 and 2 inclusively; X is selected from the group consisting of CH or N; R1 is selected from the group consisting of —CH2NH2, and R2 is selected from the group consisting of —H, —OH, —NH2 and acetyl; R3 is selected from the group consisting of —H, benzyloxycarbonyl and benzylsulfonyl; and R4 is selected from the group consisting of —OH, wherein p is an integer between 0 and 2 inclusively, Y is selected from the group consisting of —O—, —S—, —S(═O)—, —SO2—, methylene, —CH(OH)—, —CH(NH2)—, —CH(CH2—OH)—, —CH(CH2—NH2)— or —N(R6)—, R5 is selected from the group consisting of —H or a simple (C1-C3) alkyl and R6 is selected from the group consisting of —H, a simple (C1-C3) alkyl or a simple (C1-C3) acyl. These compounds are useful as anticoagulant agents as a result of their selective dual inhibition of thrombin and prothrombinase.
