Abstract: A specific anilino derivative of chelocardin having high antibiotic activity is described. This new derivative shows unusually low toxicity and consequently a very high therapeutic index as chemotherapeutic agent against gram-negative organisms.

Abstract: Triglycerides carrying the anti-inflammatory drug moiety in the 2-position and hydrocarbon acyl moieties in the 1- and 3-position exhibit excellent anti-inflammatory properties without causing the side effects often associated with the anti-inflammatory drug itself.

Abstract: Esters of 1,N.sup.6 -etheno-5'-adenosine carboxylic acid represented by the formula ##SPC1##Wherein R.sub.1 is loweralkyl, loweralkenyl, loweralkynyl or cycloalkyl; and R.sub.2 and R.sub.3 each are hydrogen or acyl, or R.sub.2 and R.sub. 3 taken together form an isopropylidene or benzylidene moiety; and the pharmaceutically acceptable acid addition salts thereof.The compounds wherein R.sub.2 and R.sub.3 are hydrogen are useful in treating cardiovascular disorders and are particularly useful as anti-anginal and anti-hypertensive agents. Compounds wherein R.sub.2 and R.sub.3 are acyl or when taken together form an isopropylidene or benzylidene moiety are intermediates useful in the preparation of the final products. (R.sub.2 and R.sub.3 = hydrogen). The final products are also useful as intermediates for preparing pharmaceutically active compounds, and, more specifically, for preparing the corresponding 1,N.sup.6 -etheno-5'-adenosine carboxamides.

Abstract: Amides of 1,N.sup.6 -Etheno-5'-adensine carboxylic acid represented by the formula ##SPC1##Wherein R.sub.1 and R.sub.2 each are hydrogen, loweralkyl, loweralkenyl, loweralkynyl or cycloalkyl, and R.sub.3 and R.sub.4 each are hydrogen, acyl, or R.sub.3 and R.sub.4 taken together form an isopropylidene or benzylidene moiety; and the pharmaceutically acceptable acid addition salts thereof.The compounds wherein R.sub.3 and R.sub.4 are hydrogen are useful in treating cardiovascular disorders and are particularly useful as anti-anginal and anti-hypertensive agents. Compounds wherein R.sub.3 and R.sub.4 are acyl or when taken together form an isopropylidene or benzylidene moiety are intermediates useful in the preparation of the final products.
