Actinomycin C is an antibiotic complex composed of actinomycin C1, C2 and C3 and produced by Streptomyces chrysomallus. Actinomycin C reversibly binds to DNA, interfering with the synthesis of RNA, prevention of RNA polymerase elongation and, consequently, with protein synthesis. Actinomycin C exert an inhibitory effect on gram-positive and gram-negative bacteria and on some fungi. However, the toxic properties of the Actinomycin C in relation to antibacterial activity is such as to preclude its use as antibiotics in the treatment of infectious diseases. Because Actinomycin C is cytotoxic, it has an antineoplastic effect which has been demonstrated in experimental animals with various types of tumor implant. This cytotoxic action is the basis for its use in the treatment of certain types of cancer.

Indenolol hydrochloride is a mixture of 1-(7-in-denyloxy)-3-isopropylamino-2-propanol monohydrochloride and 1-(4-indenyloxy)-3-isopr opylamino-2-propanol monohydrochloride. Indenolol is a non-cardioselective beta blocker used to treat hypertension.

Halquinols (halquinol) is an antimicrobial for treatment of skin infections available as topical skin pharmaceutical. Tarquinor skin cream, a dermatological preparation of halquinol 0.2% and 1% coal tar has been approved for use in New Zealand in 1962 and is in use in Australia at present. Halquinols has a broad antimicrobial activity in vitro against a wide variety of bacteria, fungi and protozoa including Candida albicans, Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis and Streptococcus pyogenes. It has a significant antimycoplasmal (MICs of 3 to 4 ug/ml) and anticryptosporidial activity at 1 or 20 uM against Cryptosporidium parvum. As some antimicrobials halquinol has been used as a growth promotor in poultry. Study of fresh water fish Catla catla treated with halquinol suggested enhanced anabolic metabolism resulting in weight gain. However, the mechanisms by which the drug improves performance are not fully understood. Halquinol was the only antimicrobial drug tested in chicken that did not affect microbial membership compared to the control group.

Butirosin is water-soluble aminoglycosidic antibiotic complex which is active against both Gram-positive and Gram-negative bacteria. Butirosin is less toxic than neomycin and shows a good antibacterial activity, including Pseudomonas aeruginosa, which is resistant to neomycin, ribostamycin and kanamycin.

Tidiacic (thiazolidine-2,4-dicarboxylic acid) is a hepatoprotective drug that acts as an antioxidant and a sulfur donor. Tidiacic is a component of tidiacic arginine that used in France for the treatment of toxic liver damage
