    Opis:
    2,6-Naphthyridine is one of the six structural isomers of pyridopyridines. This review presents most of the literature data about natural and synthetic 2,6-naphthyridine derivatives and their biological activity. The main goal of this paper is to present various methods for the preparation of 2,6-naphthyridine analogues. Compounds containing 2,6-naphthyridine moiety can be synthesized from different substrates. Most of them have been obtained by cyclocondensation of various pyridine derivatives. During the past twenty years the biological activity of 2,6-naphthyridines have been studied. Presented compounds exhibit anticancer [21, 41], antihypertension [10], and antidepression [25] activity. Some of them can be used in the treatment of heart diseases [22], appetite disturbance, and obsessive states [43, 44]. 2,6-Naphthyridine derivatives with different molecular targets, e.g. topoisomerase [41], SERT [27], and protein kinases [21, 22] inhibitors have also been reported. Many of the 2,6-naphthyridine analogues are histamine H3 [27] and serotonine 5-HT2 [42–44] receptor antagonists.

    Opis:
    Schiff bases are compounds with a functional group that contains a carbon- -nitrogen double bond with the nitrogen atom connected to an aryl or alkyl group. Schiff bases are condensation products of primary amines with carbonyl compound. Several studies showed that the presence of a lone pair of electrons on the nitrogen atom of the azomethine determine biological and chemical properties of imines. Schiff bases are generally excellent chelating agents, because of the special properties of C=N bond. Their metal complexes have been widely studied because they possess anticancer in vitro and herbicidal applications. Imines also have biological importance. Schiff bases are common enzymatic intermediates where an amine reacts with an aldehyde or ketone of a cofactor or a substrate. Imines have been reported for their biological properties such as antibacterial (E. coli, S. aureus), antifungal (C. albicans) activities. A large number of different Schiff bases are active against a wide range of protozoan (T. gypseum, P. viticola).

    Opis:
    Adenosine (Rys. 1) is a purine nucleoside playing an important role in human body. It is involved in key pathways such as purinergic nucleic acid base synthesis, amino acid metabolism and modulation of cellular metabolic status [1,2]. Adenosine acts through the four types of adenosine receptors: A1, A2A, A2B and A3 belonging to the G protein-coupled receptor family [3]. In physiological conditions this nucleoside is present in a micromolar range [5]. However, when metabolic stress occurs extracellular level of adenosine raises revealing its protective properties. Depending on an activated receptor subtype, adenosine demonstrates cardioprotective and neuroprotective activity during hypoxia or ischemia, it stimulates the immunological system [6, 7]. Besides many potential applications, adenosine is used mainly for the treatment of paroxysmal supraventricular tachycardia. Limitations are linked to a very short blood half-time and no receptor specificity [8]. This review is focused on novel literature data about synthesis of adenosine analogues with interesting biological activities. In order to influence adenosine receptor selectivity and pharmacokinetic properties a nucleoside structure can be modified in purine [14, 15, 17, 22, 26, 27, 35] or sugar ring [29, 32]. New interesting compounds are also synthesized by cyclisation of adenosine [36]. Modification of adenosine structure allowed obtaining compounds with targeted action: antiarrhythmic [11, 12], antinociceptive [9], antilipolytic [13], antiviral [29] or anticancer [35].

    Opis:
    Many 2-amino-1H-benzimidazole drugs such as antihistaminic mizolastine and norastemizole or antiparasitic mebendazole, albendazole and thiabendazole have been used in clinic [1, 2]. Benomyl and its metabolite Carbendazim are both antifungal and anticancer drugs [4]. Recently, a lot of literature has revealed that 2-amino-1H-benzimidazole derivatives could effectively inhibit the growth of various microorganisms, what suggests that 2-aminobenzimidazole compounds should have large potential as a new type of antibacterial [15] and antifungal [18] agents. A number of 2-aminobenzimidazoles have exhibited antiproliferative in vitro properties [11]. Some new compounds, containing in theirs structures 2-aminobenzimidazole, show interesting and diverse cytotoxic mechanism of action, e.g. induce apoptosis of cancer cells [13]. Some of 2-aminobenzimidazole analogues are histamine and serotonin receptors antagonists [32]. 2-Aminobenzimidazoles derivatives have been frequently found to display a variety of biological activities like anti-inflammatory, antioxidant and anticoagulant [32] properties.

    Opis:
    Pyrrolo[3,4-c]pyridine is one of the six structural isomers of the bicyclic ring system containing pyrrole moiety condensed with a pyridine nucleus. This review presents most of the literature data about synthetic pyrrolo[3,4-c]pyridine derivatives and their biological activity. S. Gabriel and J. Colman [4] discovered this isomer for the first time and named it “merimine” [Fig. 3]. The main goal of this study is the presentation of various methods for the preparation of pyrrolo[3,4-c]pyridine derivatives. Compounds containing the pyrrolo[3,4-c]pyridine scaffold can be synthesized from different substrates, but the syntheses may be classified into two main categories: annulation of pyrrole ring onto pyridine derivatives or annulation of pyridine ring onto pyrrole derivatives. Biological investigations have shown that pyrrolo[3,4-c]pyridine derivatives have a wide spectrum of actions. Most of them have been studied as analgesic and sedative agents [35–40]. Antitumor [19, 42, 45], antiviral [27], antituberculostatic [43] activities have been found. Pyrrolo[3,4-c]pyridine derivatives can also be used in the treatment of nervous [20, 41] and immune [19, 42] system diseases.

This review presents most of the literature data about synthetic pyrrolo[2,3-d]pyridazine derivatives and their biological activity. These 5,6-diazaindole analogues were first synthesized by Fischer et. al. in 1928. Compounds containing the pyrrolo[2,3-d] pyridazine scaffold can be synthesized from different substrates, but the syntheses may be classified into two main categories: annulation of pyrrole ring on to pyridazine derivatives or annulation of pyridazine ring on to pyrrole derivatives. Pyrrolo[2,3-d]pyridazine derivatives have attracted considerable interest, owing to diverse biological activities. Most of them have been studied as antitumor and antiviral. Pyrrolo[2,3-d]pyridazines can also be used as acid pump antagonist.
