Ferrocene derivatives as anti-infective agents

Infectious diseases like malaria, tuberculosis or HIV are among the leading causes of death worldwide according to WHO estimations. Nevertheless, the fight against infectious diseases is aggravated through growing development of resistance towards current drugs and due to their severe adverse effects. The introduction of the lipophilic organometallic moiety ferrocene, a compound with a sandwich-like structure, in an existing bioactive molecule is a promising tool for the development of new more efficient drugs with innovative mechanisms of action. Thus, this review summarizes recent developments in the field of ferrocene conjugation to bioactive molecules like natural products, synthetically derived drugs, peptides as well as heterobimetallic complexes. Hereby, we will provide the reader with a summary of the most potent ferrocene derivatives reported for a plethora of infectious diseases by tabulating and critically assessing the corresponding IC50 values and the minimal inhibitory concentrations (MIC). Owing to the diverse field of infectious diseases the reported ferrocene derivatives were classified according to their targets into four main groups: antiparasitic (with antimalarial agents as biggest group), antibacterial, antifungal and antiviral agents.

Isatin?azole hybrids and their anticancer activities

Isatin and azole moieties, which have the ability to form various noncovalent interactions with different therapeutic targets, are common pharmacophores in drug development. Isatin and azole derivatives possess promising in vitro and in vivo anticancer activity, and many of them, such as semaxanib, sunitinib, and carboxyamidotriazole, could be used to treat various cancers. Thus, it is conceivable that hybridization of the isatin moiety with azole may provide a valuable therapeutic intervention for the treatment of cancer. Substantial efforts have been made to develop isatin?azole hybrids as novel anticancer agents, and some of the isatin?azole hybrids exhibited considerable activity. This review emphasizes isatin?azole hybrids with potential anticancer activity, covering articles published between 2010 and 2019. The structure?activity relationships as well as the mechanisms of action are also discussed to provide insights for the rational design of more effective candidates.

Synthesis, ADME evaluation, and in vitro antimycobacterial studies of a novel series of 2-thiazolylimino-5-arylidene-4-thiazolidinone derivatives

Background: The emergence of multi-drug resistant and extensively drug-resistant cases of tuberculosis has lead to the search for new structural classes of anti-tuberculosis drugs. There are many reports on antimycobacterial screening of compounds containing the 4-thiazolidinone moiety. The 5-arylidene moiety in the 2-heteroarylimino-5-benzylidene-4-thiazolidinone scaffold plays an important role in antimicrobial activity against Gram-positive and Gram-negative bacteria, yeasts and moulds. Objective: To synthesize 2-thiazolylimino-5-arylidene-4-thiazolidinone derivatives, with different substituents on the aryl ring, and evaluate their in vitro antimycobacterial activity against M. tb H37Rv. Methods: The derivatives were synthesized by previously reported methods, and structures confirmed by spectral data. Qikprop, the ADME prediction program was used in predicting pharmacokinetic properties of the derivatives, which helped in designing and synthesis of novel and more potent analogs. In vitro antimycobacterial activity against drug-sensitive M. tb H37Rv was performed in BACTEC-460 TB radiometric system. Results: The synthesis and antimycobacterial activities of 2-thiazolylimino-5-arylidene-4-thiazolidinone derivatives have been reported. The chemical modifications not only altered the physicochemical properties but also pharmacological activities. The compounds exhibited moderate to excellent in vitro activity (88-99.7% inhibition) against M. tb H37Rv, and few demonstrated >99% inhibition at 6.25 mug/mL. The activity was considerably affected by various substituents and compounds with di- and trisubstitutions on the aromatic ring of the 4-thiazolidinone were more active. Conclusion: These preliminary but encouraging results indicate that 2-thiazolylimino-5-arylidene-4- thiazolidinones are promising scaffolds for design and development of new molecules for antimycobacterial activity. Several compounds were identified as novel and potential lead for design and synthesis of new antimycobacterial agents.
