Guanosine is an endogenous guanine nucleoside. Guanosine was shown to be protective in several in vitro and/or in vivo experimental models of central nervous system (CNS) diseases including ischemic stroke, Alzheimer's disease, Parkinson's disease, spinal cord injury, nociception, and depression. The mechanisms underlying the neurobiological properties of guanosine seem to involve the activation of several intracellular signaling pathways and a close interaction with the adenosinergic system, with a consequent stimulation of neuroprotective and regenerative processes in the CNS. Several guanosine analogues, i.e. acyclovir (and its oral prodrug valaciclovir), penciclovir (in its oral prodrug form, famciclovir) and ganciclovir, are widely used for the treatment of herpesvirus (i.e. HSV-1, HSV-2, VZV and HCMV) infections.

Palmatine is a protoberberine alkaloid. Palmatine is major component of herbal preparations mainly used in traditional medicine Chinese, Korean and Indian. Palmatine can be found in various medicinal plants such as Coptis chinensis, Rhizoma coptidis, Corydalis yanhusuo, Radix tinosporae, among others. It exerts diverse pharmacological and biological properties. Palmatine has been proposed as a promising DNA phototherapy drug, notably due to its ability to produce in situ singlet oxygen only when interacting with DNA.

NADIDE (NAD+) is a coenzyme composed of ribosylnicotinamide 5'-diphosphate coupled to adenosine 5'-phosphate by pyrophosphate linkage. NADIDE was marketed under the brand name Enada. Although Enada (NADH) is marketed as a nutritional supplement, Birkmayer Pharmaceuticals has launched two clinical trials to prove scientifically that Enada is effective. Before these studies could get started they had to also prove to the Food and Drug Administration (FDA) that the stable oral form of Enada (NADH) is a safe substance. Since the mid-‘80s more than 3,000 parkinsonian patients have received NADH, either as intravenous infusion or in the form of oral tablets. Enada (NADH) is the world‘s first and only stabilized, absorbable, patented, tablet-form NADH dietary supplement. It is now available to everyone whose lifestyle demands increased energy, vitality and mental clarity. In other words, it is beneficial not only for patients suffering from chronic fatigue syndrome, Alzheimer‘s disease, depression or Parkinson‘s disease, but for any normal, healthy individual whose lifestyle demands more energy. NADIDE (NADH) may be considered as a therapeutic adjunct for cancer patients to protect them against the general toxic effects of substances such as doxorubicin or cisplatin by stimulating the DNA repair system and by promoting normal cellular biosynthetic responses after chemotherapy. NADH seems to exhibit a chemo preventive effect.

Morantel (1,4,5,6-tetrahydro-1-methyl-2-[2-(3-methyl-2-thienyl)ethenyl pyrimidine) is a tetrahydro-pyrimidine anthelmintic, differing from the related analogue pyrantel by the presence of a methyl group on the thiophene ring. Morantel tartrate, manufactured by Pfizer, Inc., was approved in the United States for use in cattle in 1981, and entered the market in early 1982. Three formulations have been approved in the United States: RUMATEL® Medicated Premix-88; RUMATEL Cattle Wormer Bolus, and PARATECT FLEX™ Diffuser, a sustained release bolus. It is intended to treat roundworms and tapeworms. Morantel is administered in lactating and non lactating cattle as morantel tartrate as a slow-release bolus (11.8 g morantel base per animal) or as a single oral dose of 6 to 7.5 mg morantel base/kg bw and in pigs at a single dose equivalent to 7.5 mg base/kg bw. In sheep, the citrate salt is administered at a single dose equivalent to 5 to 6 mg morantel base/kg bw. Morantel acts as a potent agonist at the acetylcholine receptors on the muscle cells of nematodes. Activation of the acetylcholine receptors induces a prolonged, spastic paralysis of the worms and expulsion from the host. It also been reported to block neurotransmission in vertebrates, to possess nicotine-like properties and to mimic acetylcholine at receptors in autonomic ganglia, adrenal medullae and respiratory tissues. Morantel and its salts are not used in human medicines.

Carcinine (beta-alanylhistamine) is a natural imidazole-containing peptide found in the non-protein fraction of mammalian tissues and possesses antioxidant and hydroxyl radical scavenging properties. Carcinine is also a selective histamine H3 antagonist.
