Background: Vitiligo is a chronic depigmentation disorder caused by the selective destruction of melanocytes, with limited effective treatment options, particularly in resource-limited regions. Nigella sativa (black cumin seed, BCS) has traditionally been used for various skin ailments, including pigmentation disorders. Objectives: This study aimed to evaluate the pro-melanogenic activity of a 96\% ethanol extract of Indonesian BCS (EE BCS) in B16F10 cells. Methods: Phytochemical profiling was performed using gas chromatography{\textendash}mass spectrometry (GC-MS), and thymoquinone (TQ) content was quantified by highperformance liquid chromatography (HPLC). Cell viability (MTT assay), tyrosinase activity (L-DOPA assay), and melanin content were measured. Results: GC-MS identified 9,12-octadecadienoic acid methyl ester (E,E) as the predominant compound (45.88\%), while HPLC confirmed a relatively low TQ concentration (0.04\%). EE BCS maintained \>90\% cell viability at concentrations up to 12.50 ppm and exhibited an IC50 of 56.41 ppm. Tyrosinase activity significantly increased at 6.25 ppm (136.40\%; p \< 0.05) and 12.50 ppm (228.10\%; p \< 0.01), accompanied by a significant elevation in melanin content (226.00\%; p \< 0.05 and 266.90\%; p \< 0.01 respectively). Conclusion: EE BCS can effectively promote melanogenesis, despite containing low levels of thymoquinone, potentially through synergistic actions of its phytochemical constituents. Given its region-specific phytochemical richness, Indonesian N. sativa extract holds promise as a natural therapeutic candidate for vitiligo. Further in-vivo and clinical validation is warranted.

Aim: The aim of this study is to finding inhibitor potential from several compounds in gambir plant by using in vitro MTT assay and study interaction with molecular docking. The interaction of amino acids on the binding site with substances in the gambir plant was analyzed to determine its potential as a herbal-based therapy candidate for pulmonary fibrosis. Material and Methods: Protein target using TGFβ1 and NF-κB and compounds from gambir plant ((+)-Catechin. Epigallocatechin gallate, (+)-Epicatechin, Gambiriin A1, Gambiriin A2, Gambiriin B1, Gambiriin B2, Gambiriin C, Procyanidin B1, Procyanidin B3). Result: The results from docking analysis observed that compounds from gambir fruit contain anti-fibrotic activity which act by inhibiting DNA transcription of NF-κB and TGF-β1receptors. The compound Procyanidin B3, an essential amino acid, contains a hydrogen bond with the greatest NF-κB inhibitory activity on Gly214 and Lys337. Compounds from Uncaria gambir (Hunter) Roxb. can be an inhibitor to TGFβ1, all the compounds are on the active site of TGFβ1, and use native ligand which is an inhibitor of TGFβ1 (Naphtyridine). The positive compound catechin has the highest inhibitory activity. Gambiriin B1 and Gambiriin A2 are the most identical compounds with similar affinity binding value. Uncaria gambir (Hunter) Roxb. is already a proven antifibrotic which is further confirmed by (IC50: 19,255 {\textpm} 1.08 μg/ml, p \< 0.05) in A549 cell line. Conclusion: The results demonstrated that Gambiriin have cytotoxic effects and was found potentially as anti-fibrotic by MTT assay and in silico evaluation.
