Mannich base is a versatile compound that can be easily modified to introduce different functional groups, allowing for the creation diverse selection of items with varying features. Additionally, the Mannich reaction is a valuable tool in organic synthesis, due to the fact it provides an effortless and efficient approach for synthesizing C-N bonds. Overall, The Mannich base and even its derivatives are essential in many aspects of chemistry and its complexes are in the pharmaceutical industry. Studies have revealed that it shows good anti-cancer, anti-mycobacterial, remarkable anti-HIV, anti-tubercular, anti-convulsant, anti-fungal, antiviral, antitumor, cytotoxic activities and in industrial applications such as in the creation of polymers, surface activity agents, deter gents and resins. The presence of the basic Mannich sidechain has shown marked antimalarial, anti - inflammatory, analgesic and anti - microbial activities. These compounds have also been shown to inhibit corrosion, as well as antioxidant and reducing agents. This review article shows the definition, importance and different applications of Mannich base ligands with transitional metal. These complexes exhibit potent anti-microbial, antiviral, and anti-cancer activities, showcasing their potential in pharmaceutical research and drug development. Moreover, the luminescent properties of Mannich base metal complexes have been harnessed for applications in optoelectronics and sensing. Their tunable emission profiles make them suitable candidates for various sensing platforms and light-emitting devices Mannich base metal complexes.

Corrosion inhibitions in corrosive solutions of hydrochloric acid for mild steel by chemical compound 3-acetyl-4-(4-bromophenyl)-6-2-oxo-2H-chromen-3-yl pyridine-2(1H)-one (ABCP), was conducted and the chemical structure was elucidated The Nuclear Magnetic Resonance (H-NMR) and Fourier Transform Infrared (FT-IR) spectroscopic techniques. The compound ABCP had been investigated at 25 ˚C via weight loss technique. The outcomes show that the ABCP displays great performances as an inhibitor for mild steel in 0.5 M hydrochloric acid. Inhibition efficiency increments with expanding of concentration and become 98.4% at the highest studied concentration. The studies have demonstrated a reverse association between corrosion rate (CR) and inhibition efficiency (IE percent), as IE increases while CR decreases with an increased concentration. In the presence of ABCP, inhibitory efficiency was up to 98.4% at 25°C in presence of ABCP (0.5 mM). IE drops notably at 65°C with an increased temperature. By means of FT -IR and NMR spectroscopy approaches and physical properties through melting point and Thin Layer Chromatography (TLC), the chemical structure of the tested inhibitor has been clarified.
