The Macadamia genus of the Proteaceae family, which can be found mainly in the southern hemisphere, has many benefits in some disease treatments. Phytochemical compounds and pharmacological activities of this genus were comprehensively reviewed in this article. This article was written by collecting and reviewing a minimum of 50 scientific articles in PubMed, Google Scholar, Science Direct, Elsevier, and PubChem that contain the phytochemical compounds and pharmacological activities of the Macadamia genus. The articles were published in the last 15 years, a minimum of 20 articles in the last 2 years, and they also must have a DOI. The phytochemical compounds that comprised of flavonoid, proanthocyanidin, and other polyphenols compounds. These phytochemical compounds can promote a wide range of pharmacological activities such as antioxidant, anti-inflammatory, anti-dyslipidemia, dietary controlled, antimicrobial, chemopreventive, and NAFLD prevention. Nevertheless, many investigations on phytochemical compounds and pharmacological activities only focussed on a few parts of a plant, especially nuts. Therefore, further research is needed to determine the other parts of Macadamia genus plants' potential chemical compounds and pharmacological activities.

The genus Nepenthes (Nepenthaceae) has been utilized in folk medicine for a long time in India and Southeast Asia countries. They are used in the treatment of leprosy, cholera, night blindness, gastrointestinal discomfort, dysentery, stomachache, and bed-wetting among others. This review highlights the ethnobotanical uses, phytochemicals, and pharmacological activities of both crude extracts and pure bioactive compounds of Nepenthes spp. The phytochemical compounds isolated from Nepenthes species include flavonoids, terpenoids, tannins, alkaloids, and steroids among other phytochemicals. A wide range of pharmacological activities was exhibited by the crude extracts and pure bioactive components such as antibacterial, antifungal, antimalarial antioxidant, antidiabetic, antiosteoporotic, anti-inflammatory, cytotoxicity, and hypolipidemic activities. This review revealed that many active compounds are present in Nepenthes spp. However, many pharmacological screenings such as anticancer, antiviral, wound healing, antihelminthic, antidiarrheal properties, among others have not been carried out yet. Therefore, more biological investigations and phytochemical screenings are required to fully explore the genus Nepenthes which may lead to development of new therapeutic agents.

Biflavonoids, composed of two monoflavonoid residues, occur naturally in angiosperms, bryophytes, ferns, and gymnosperms. More than 592 biflavonoids have been structurally elucidated, and they can be classified into two groups of C-C and C-linear fragments-C, based on whether the linker between the two residues contains an atom. As the linker can be established on two arbitrary rings from different residues, the C-C type contains various subtypes, as does the C-linear fragment-C type. Biflavonoids have a wide range of pharmacological activities, including anti-inflammatory, antioxidant, antibacterial, antiviral, antidiabetic, antitumor, and cytotoxic properties, and they can be applied in Alzheimer’s disease and Parkinson’s disease. This review mainly summarizes the distribution and chemistry of biflavonoids; additionally, their bioactivities, pharmacokinetics, and synthesis are discussed.

In this review article data is collected regarding the various derivatives of coumarin and oxadiazole as both these have wide range of biological activities and they can be further modified to synthesize more effective and potent drugs. Coumarin class of organic compounds consists of 1,2-benzopyrone ring system as a basic parent scaffold. These benzopyrones are subdivided into alpha-benzopyrones and gamma benzopyrones; with coumarin class of compounds belonging to alpha-benzopyrones. Since the last few years, coumarins were synthesized in many of their derivative forms. Their pharmacological, therapeutic and biochemical properties depend upon their pattern of substitution. Coumarins exhibit a wide range of pharmacological activities, which includes anti-diabetic, anti-viral, anti-microbial, anticancer, anti-oxidant, anti-parasitic, anti-helminthic, anti-proliferative, anti-convulsant, anti-inflammatory and antihypertensive activities. 1,3,4-Oxadiazole is a heterocyclic compound containing an oxygen atom and two nitrogen atoms in a five-membered ring. It is derived from furan by substitution of two methylene groups (=CH) with two pyridine type nitrogens (-N=). There are three known isomers: 1,2,4-oxadiazole, 1,2,3-oxadiazole and 1,2,5- oxadiazole. Oxadiazole moiety shows antimicrobial, anticancer and anti-inflammatory activity and suitably substituted 1,3,4-oxadiazole having biological activities like antimicrobial, anticancer and other biological activities.
