Alkylaminophenols are synthetic derivatives well known for their anticancer activity. In this work, we report the antimicrobial and antioxidant activity of such compounds. A series (4,5,6) of alkylaminophenol compounds were prepared with fairly good yields by Petasis reaction. Synthesized compounds were characterized by 1 H-NMR and 13 C-NMR. The obtained compounds were tested against Gram-positive and Gram-negative bacteria. The compound 4 showed antimicrobial activity at a concentration of 10 mg/mL, while the 6 compound showed activity on S. aureus. Phenolic compounds have attracted attention due to their proximal and antioxidant activities. Since alkylaminophenols have phenolic structure, their antioxidant activity has been investigated. Thus, drug-active substances with high antioxidant capacity against diabetes, heart disease, and cancer were synthesized.

Ficaria verna Huds. is a plant belonging to the Ranunculaceae family, known as mole grass and celandine among the people. It is known to have antiinflammatory and anti-haemorrhagic pharmaceutical effects. In this study, it was aimed to determine the antimicrobial effect of different concentrations of F. verna extracts obtained from methanol, ethanol and chloroform and the antioxidant activity of different concentrations of the extract obtained from methanol. In the results obtained, the best antimicrobial effect (17-20 mm) against Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Bacillus megaterium, Salmonella thypii and Candida albicans was determined in the methanol extract of F. verna at a concentration of 1000 µg. It was observed that the scavenging effect of the DPPH radical of F. verna increased depending on increasing concentrations.

Zinc finger (ZnF) proteins are the largest transcription factors family. They constitute of nine subgroups including Cys2His2, Cys3His, Cys3HisCys4, Cys2HisCys5, Cys4HisCys3, Cys2HisCys, Cys4, Cys6 and Cys8. ZnFs perform tasks of recognizing DNA, packaging RNA, transcriptional activity, regulating apoptosis, folding and collecting proteins, and binding lipids. One of the largest subgroups of these proteins is ZF-Cys2His2, containing SIZ1, ZAT, ZAT7, ZFP1, ZFP252, DST, ZFP1, SIZF3, ZFP179, ZjZFN1, SICZFP1, and ZF-Cys2His2 proteins are found in plants tissues and fulfill important tasks in their defense to struggle with biotic and abiotic stresses (i.e., salt, drought, cold, oxidative). The aim of this chapter is to reveal importance of ZF-Cys2His2 proteins against various stress conditions.

Alchemilla genus, which belongs to the Rosaceae family, is a medicinal plant used for various purposes among the people. Species of this genus are known in Turkish folk medicine as lion claw or hazelnut grass. Especially, they are used mainly women’s illnesses, in gastritis, anti-inflammatory, as carminative, and in the treatment of wound. Besides the antimutagenic effect of Alchemilla alpina L., its above-ground parts are used for antimycotic purposes in the form of tea or oral care water. In this study, it has been aimed to determine the antimicrobial effect of the above-ground parts of Alchemilla alpina extracts obtained from methanol, ethanol and chloroform and the antioxidant activity of different concentrations of the extract obtained from methanol. The antimicrobial activity of methanol, ethanol and chloroform extracts of the above-ground parts of A. alpina has been determined according to disk disc diffusion method. In the results obtained have been showed that these extracts inhibited the growth of some bacteria (Staphylococcus aureus ATCC25923, Escherichia coli ATCC25322, Klebsiella pneumoniae ATCC700603, Bacillus megaterium DSM32) and yeasts (Candida albicans FMC17 and Candida glabrata ATCC66032) at different rates (8-23 mm). The antioxidant activity of different concentrations (1.25, 2.5, 5 and 10 mg/ml) of the above-ground parts of A. alpina extract obtained from methanol has been determined according to the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging capacity method. In the results obtained, it has been observed that the effect of removing DPPH radical of A. alpina increased depending on increasing concentrations.
