Introduction: Prolonged exposure to stress can contribute to depressive episodes. Preclinical studies have shown that stimuli like environmental enrichment (EE) can produce beneficial effects against stress by positively modulating neuroplasticity, neurochemistry, and behaviour. Hence, we explored whether exposure to EE can augment the neuroprotective activities of Celastrus paniculatus (CP) and Tribulus terrestris (TT) in stressed conditions. Materials and Methods: Rats were placed in immobilisation bags and stressed for two hours a day for ten days. After that, these stressed rats were treated by CP or TT, alone or in combination with enriched housing. Behavioural analysis in elevated plus maze, open field, forced swim and sucrose preference tests. The novel object recognition test and the rewarded alteration test on the T-maze were used to assess working memory. The brain-derived neurotrophic factor, interleukin-6, and tumour necrotic factor-alpha were measured in the hippocampus and prefrontal cortical tissues following stress and herbal treatment combined with an enriched environment. Results: We found that Celastrus paniculatus and Tribulus terrestris, combined with an enriched environment, produced a synergistic neuroprotective effect. CP + EE and TT + EE improved working memory and recognition memory in CIS animals, but they also reduced anxiety and depressive-like behaviours. TNF-α and IL-6 levels were decreased while brain-derived neurotrophic factor levels were raised in the frontal cortex and hippocampus regions, respectively. Conclusion: Our results show that living in an enriched environment can improve CP and TT neuromodulatory activities, highlighting the potential of combining sensory-motor interventions with herbal remedies for psychiatric disorders.

Objective: Andrographis paniculata has long been a traditional medicinal plant in Indonesia. This study is intended to evaluate the anti-pro-inflammatory cytokines of 98\% ethanol extract of A. paniculata by in vitro and in silico approaches. Inhibition of pro-inflammatory cytokines is also one of the therapies in treating COVID-19. Methods: The molecular docking approach was utilized as a first screening to evaluate the potential for suppression of macrophage cell activation; an ADMET prediction test was performed to determine the pharmacological, pharmacokinetic, and toxicity as a therapeutic target. TNF-α, IL-1{\ss}, and IL-6 levels were measured using an ELISA method to investigate anti-cytokine pro-inflammatory activity in LPS-induced RAW 264.7 macrophage cells. LC-MS/MS was used to identify additional metabolite compounds. Results: Ethanol extract containing particular metabolites 14-Deoxyandrographoside and 14-Deoxy-17-hydroxyandrographolide inhibited TNF-α and IL-1β by 100\% and IL-6 by 85.59\%, respectively. While compared to the Dexamethasone molecule as a positive control, preliminary screening and ADMET prediction for the metabolite compound 14-Deoxyandrographoside exhibited relatively high binding stability to the CD14 receptor by -7.5 kcal/mol and was safe against various ADMET indications. Conclusions: This study reveals that the compound 14-Deoxyandrographoside in pure ethanol extract is a potential anticytokine agent candidate for treating pro-inflammatory cytokines, including COVID-19 infection.
