A spectrum of biological activities is displayed by imidazole derivatives and 2- mercaptobenzimidazole, such as antifungal, antioxidant, anti-inflammatory, and antimicrobial actions, leading to their therapeutic flexibility apart from epilepsy treatment. Imidazole derivatives mechanistically modulate Gamma-Aminobutyric Acid (GABA) receptors, inhibit ion channels, and exert neuroprotective effects, enabling them to be used for seizure control. Their mechanisms of action involve modulation of oxidative stress pathways as well as providing neuroprotective effects against epilepsy. In terms of structure, both imidazole and 2-mercaptobenzimidazole derivatives have gone through extensive structure-activity relationship studies to enhance their biological and pharmacological aspects.

Several PAHs, including Pyrene (PYR), Chrysene (CHY), Benz[a]anthracene (BaA), Benzo[a]pyrene (BaP), Fluoranthene (FLU) Indenol [1,2,3-cd] pyrene (INP), Benzo[ghi]perylene (BghiP), and, Dibenz [a, h] anthracene (DBA) have been identified by the International Agency for Research on Cancer (IARC) as carcinogenic, mutagenic, and teratogenic.

From lignin, we can produce natural binders and adhesives, among other products. With hemicellulose, we can produce emulsifiers, resins, or lubricants, for example. Using cellulose, we can produce fuels, such as ethanol and biodiesel, or even solvents. Fuels from biorefineries can replace, totally or partially, non-renewable fuels that pollute the environment, such as oil. Considering the climate emergency, we are experiencing, the tendency to reduce the availability of oil, and the negative environmental impacts caused by it, fuels obtained through the processing of renewable plant materials present themselves as a good alternative to replacing fossil fuels. Firstgeneration ethanol (1G) can be obtained by fermenting, for example, sugar cane juice. Secondgeneration (2G) ethanol can be obtained by processing lignocellulosic waste. In this process, there must be pre-treatment and hydrolysis of the biomass before the fermentation and distillation processes. Third-generation ethanol (3G) can be obtained through the fermentation of substrate present in microalgae. Fourth-generation ethanol (4G), in turn, involves the integration of production processes from other generations, increasing the efficiency of 2G and 3G processes for ethanol production.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Objective: &lt;/strong&gt;The objective of this study was to investigate the scenario of patent registrations filed both on the Google Patents platform and Espacenet, which proposes the production of fuels from biorefineries, that are renewable and sustainable.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;Although there are other lignocellulosic products originating from biorefineries, we will limit ourselves to patents aimed at the production of cellulosic ethanol. The search covered patents filed in the last 5 years (2019-2023). The 10 patents from each of the 3 biotechnological areas were selected, classified as agriculture, environment, and bioprocesses/bioengineering, totaling 30 patents to be analyzed.

The main strategies for the production of renewable and sustainable fuels in the context of biorefineries explore mechanisms for reusing agricultural waste, pre-treatment of residual biomass, and reuse of biorefinery waste, among other technologies.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;The future perspective is that the production of renewa","PeriodicalId":21064,"journal":{"name":"Recent patents on biotechnology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143773182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
