Phytochemicals can also interfere with the signaling pathways involved in inflammation, such as nuclear factor-kappa B (NF-κB), mitogen-activated protein kinases (MAPKs), cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS). Inflammation is a common feature of many chronic diseases, such as arthritis, diabetes, obesity, asthma and cancer. Some examples of anti- inflammatory phytochemicals are polyphenols, terpenoids, alkaloids, glucosinolates and organosulfur compounds.⁷

 Antimicrobial activity: Phytochemicals can inhibit the growth and survival of various microorganisms, such as bacteria, fungi, viruses and parasites. Phytochemicals can act on different targets of the microbial cells, such as cell wall, membrane, DNA, RNA, proteins and enzymes. Phytochemicals can also modulate the host immune system to enhance the resistance against infections. Antimicrobial phytochemicals can be used as alternative or complementary therapies for infectious diseases, especially in the context of antibiotic resistance. Some examples of antimicrobial phytochemicals are alkaloids, flavonoids, terpenoids, phenolics and organosulfur compounds.⁸

 Anticancer activity: Phytochemicals can exert various effects on cancer cells and tumor microenvironment to prevent or inhibit carcinogenesis. Phytochemicals can modulate the expression and activity of genes and proteins involved in cell cycle regulation, apoptosis, autophagy, angiogenesis, metastasis and drug resistance. Phytochemicals can also modulate the immune system to enhance the antitumor response. Anticancer phytochemicals can be used as chemopreventive or chemotherapeutic agents for different types of cancers. Some examples of anticancer phytochemicals are curcumin, resveratrol, quercetin, berberine and ginkgolides.⁹
