The compounds have enzyme inhibitor activity e.g., renin inhibition angiotensin converting enzyme inhibition. BACKGROUND OF THE INVENTION The present invention is concerned with novel compounds (substituted amino acids and dipeptides) which inhibit renin and in some instances also inhibit angiotensin converting enzyme (ACE). The present invention is also concerned with pharmaceutical compositions containing the novel compounds of the present invention as active ingredients, with thier use for treating renin and/or ACE associated conditions, with diagnostic methods which utilize these compounds, and with processes for their preparation. Small peptide inhibitors of renin have been reported by Kokubu et al. (Biochem. Biophys. Res. Communs, 118, 929 (1984)) and by Fehrentz et al. (Febs. Letts., 167, 273 (1984)), who described peptide aldehyde inhibitors. R. Matsuda et al. in European Patent Application 128,762 (Sankyo Co., Ltd., 1984) also disclose tripeptide aldehydes as renin inhibitors. Some of the compounds disclosed in the present invention also inhibit angiotensin-converting enzyme. Peptides containing aminophosphonic acids as the carboxyl-terminal components, which are inhibitors of A.C.E. have previously been reported by Y. Kido et al., in J. Antibiot. (Tokyo), 37, 965-9 (1984) and in Japanese Patent J59187-790-A (Kyowa Hakko Kogyo KK) (1984). Also, phosphinylalkanoyl substituted proline analogs which inhibit A.C.E. have previously been described by E. Petrillo et al., U. S. Patents No 4,168,267; 4,337,201 (E. R. Squibb and Sons, 1979, 1982). Compounds of no more than two amino acids or the equivalent, which incorporate phosphorous-containing elements as the carboxyl-terminal or next-to carboxyl-terminal component have been discovered. They are potent renin inhibitors and may be orally acive.

Calcium Channel Blockers: nifedepine; nitrendipine, verapamil; diltiazam. Other Antihypertensive Agents: aminophylline; cryptenamine acetates and tannates; deserpidine; meremethoxylline procaine; pargyline; trimethaphan camsylate; and the like, as well as admixtures and combinations thereof. Typically, the individual daily dosages for these combinations can range from about one-fifth of the minimally recommended clinical dosages to the maximum recommended levels for the entities when they are given singly. Coadministration is most readily accomplished by combining the active ingredients into a suitable unit dosage form containing the proper dosages of each. Other methods of coadministration are, of course, possible. The novel compounds of the present invention possess an excellent degree of activity in treating hypertension and congestive heart failure. For these purposes the compounds of the present invention may be administered orally, parenterally, by inhalation spray, or rectally in dosage unit formulations containing conventional non-toxic pharmaceutically acceptable carriers, adjuvants and vehicles. The term parenteral as used herein includes subcutaneous injections, intravenous, intramuscular, intrasternal injection or infusion techniques. In addition to the tr atment of warm- blooded animals such as mice, rats, horses, dogs, cats, etc., the compounds of the invention are effective in the treatment of humans. The pharmaceutical compositions may be in the form of a sterile injectable preparation, for example as a sterile injectable aqueous or oleagenous suspension. This suspension may be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally-acceptable diluent or solvent, for example as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil may be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid find use in the preparation of injectables. The peptides of this invention may also be administered in the form of suppositories for rectal administration of the drug. These compositions can be prepared by mixing the drug with a suitable non-irritating excipient which is solid at ordinary temperatures but liquid at the rectal temperature and will therefore melt in the rectum to release the drug. Such materials are cocoa butter and polyethylene glycols. Dosage levels of the order of 0.1 to 4.0 grams per daj parenterally are useful in the treatment of the above indicated conditions. Oral doses are 3-10 times higher. For example, renin- associated hypertension and hyperaldosteronism are effectively treated parenterally by the administration of from 1.0 to 50 milligrams of the compound per kilogram of body weight per day. The amount of active ingredient that may be combined with the carrier materials to produce a single dosage form will vary depending upon the host treated and the particular mode of administration. It will be understood, however, that the specific dose level for any particular patient will depend upon a variety of factors including the activity of the specific compound employed, the age, body weight, general health, sex, diet, time of administration, route of administration, rate of excretion, drug combination and the severity of the particular disease undergoing therapy. Thus, in accordance with the present invention there is further provided a pharmaceutical composition for treating hypertension and congestive heart failure, comprising a pharmaceutical carrier and a therapeutically effective amount of a compound of the formula I. Also, in accordance with the present invention there is still further provided a method of treating hypertension and congestive heart failure, comprising administering to a patient in need of such treatment, a therapeutically effective amount of a compound of the formula I. The renin inhibitory compounds of the present invention may also be utilized in diagnostic methods for the purpose of establishing the significance of renin as a causative or contributory factor in hypertension or congestive heart failure in a particular patient. For this purpose the present compounds may be administered in a single dose of from 0.1 to 10 mg per kg of body weight. Both in vivo and in vitro methods may be employed. In the in vivo method, a novel peptide of the present invention is administered to a patient, preferably by intravenous injection, although other routes of parenteral administration are also suitable, at a hypotensive dosage level and as a single dose, and there may result a transitory fall in blood pressure. This fall in blood pressure, if it occurs, indicates supranormal plasma renin levels. Some of the compounds of formula I also have angiotensin converting enzyme (ACE) inhibitor activity. This activity augments renin inhibition in lowering blood pressure and in treating congestive heart failure. Treatment dosage and mode for this utility is generally the same as set out earlier. The preparation of the formula I compounds is illustrated in some of the examples below and in general proceeds as follows: a) Coupling of an amino-protected form of E to G, followed by b) amino protecting group removal from E-G and c) coupling A to the resulting amino group of E-G. The phosphorous-containing component E, as well as the component A may contain functionality which requires protection during the coupling reactions. Protecting groups, among those well-known in peptide synthesis, are chosen so as to be compatible with the coupling steps, yet easily removable afterwards. Among those utilized for amino group protection are the t-butoxycarbonyl (BOC), benzyloxycarbonyl (CBZ), 9-fluorenylmethyloxycarbonyl (FMOC), and benzyl groups. Carboxylic acids are protected as the methyl, ethyl, benzyl, or t-butyl esters. Phosphonic and phosphinic acids are protected as the methyl or ethyl esters. The coupling procedures referred to above include those brought about by use of dicyclohexylcarbodiimide/ 1-hydroxybenzotriazole and of disuccinimido oxallate (K. Takeda et al., Tetrahedron Lett., 24, 4451-54 (1983)). In many cases, both carboxylic and phosphonic (or phosphinic esters) may be hydrolyzed along with amino protecting groups as the last step in the synthesis. In these cases, treatment of the phosphorous-containing peptide analog with 30% hydrobromic acid in acetic acid, with 6N hydrochloric acid, or with aqueous sodium hydroxide, followed by purification of the resulting deprotected material by ion-exchange chromatography or reverse-phase HPLC, provides the desired product. In instances where A-E-G possesses a carboxyl-terminal amide function (R3=NH2, , or ), the fully coupled material A-E may be treated with 1 equivalent of lithium hydroxide (0.1 N) to hydrolyze selectively a carboxylic ester function in E. Standard coupling procedures may then be used to couple the resulting free carboxylic acid to an appropriate amine. This is followed by removal of the remaining protecting groups as described above. Alternatively the amide formation may be carried out prior to coupling of the component E-G to the A unit. Preparation of the phosphorous-containing components E are carried out as illustrated in the examples to follow. The 1-aminoalkylphosphonous acids used as starting materials in the examples below are prepared as illustrated in the examples and can be resolved to give optically active materials by the method of Baylis et al. (J. Chem. Soc. Perkin Trans 1, 2845-53 (1984)). Compounds derived from both the optically active and racemic materials are claimed in the present invention. The 1-aminoalkylphosphonic acids used in the examples below are prepared as described and can be resolved to give the optically active materials by the procedure of Kafarski et al., Can. J. Chem., 60, 3081-84 (1982), or can be prepared in optically active form by the method of Huber et al., Tetrahedron Lett., 3049-3052 (1979). Compounds derived from both the optically active and racemic materials are claimed in the present invention. When the amino group of the unit E which is to be coupled to A bears an N-methyl group (R6 = -CH3), procedures well known in peptide synthesis are used to couple A to E or E-G. In general, the mixed anhydride procedure (with pivaloyl chloride and N-methylmorpholine) is used, as illustrated by R. M. Wenger, Helv. Chem. Acta., 1984, 67, 502-525. This procedure is also utilized in formation of E-G when G is and R8 is other than hydrogen and in the preparation of G when R9 is and R6 R6 is methyl.
