The objective of this article is therefore to analyze the link between economic growth and environmental degradation in the case of 14 countries of sub-Saharan Africa. From WDI data over the period from 1970 to 2018, we estimated the Environmental Kuznets curve (CKE) in panel by the within estimator, based on the one-way fixed effect method. The results indicate that the CKE is not validated, but that there is a linear and positive relationship between economic growth and pollution.As a measure of robustness, we proceed to another estimation of our model using the Two-Way fixed effects method. The results confirm once again the non-validation of the Environmental Kuznets Curve (EKC) for our panel, and confirm the existence of a linear and positive relationshipbetween economic growth and pollution.We have announced to these countries to set up public policies aimed at industrialization and environmental protection.

In this review paper, we wish to discuss and summarize indazoles synthesis and functionalization such as bromination, iodination, N-alkylation, N-arylation, Suzuki–Miyaura cross coupling and direct arylation. Then, in the second part, various drugs containing indazole system and the biological properties of indazole derivatives, including antiinflammatory, antimicrobial, anti-HIV, anticancer, antagonist TRPV1, antihypertensive, and other applications will be presented and discussed.
