1. Aloe-emodin-8-O-beta-D-glucopyranoside shows moderate bioactivity against human Protein Tyrosine Phosphatase 1B (hPTP1B) in vitro.
1. Aloin A/B (1) and aloin-6'-O-acetate A/B (2) inhibited growth of several bacterial and fungal pathogens with minimum inhibitory concentration (MIC) from 10 to 400 microg/mL and 800 to 1000 microg/mL.
1. The extract of A. vera and its active ingredient aloin cause melanin aggregation leading to skin lightening via alpha adrenergic receptor stimulation, the result opens new vistas for the use of A. vera regarding its clinical application as a new nontoxic melanolytic agent for the treatment of hyperpigmentation.
2. Dietary supplementation of aloe components (aloin, aloesin and aloe-gel) can ameliorate intestinal inflammatory responses in a 3% dextran sulfate sodium (DSS)-induced ulcerative colitis rat model, in particular, aloesin is the most potent inhibitor.
1. Alpha-Amyrin is an antineoplastic agent.
2. Alpha-Amyrin is trypsin and chymotrypsin inhibitor.
3. Alpha-Amyrin induces proliferation of human keratinocytes.
4. Alpha-Amyrin can as a hepatomodulatory potent to feasibility for a promising liver curative drug.
1. alpha-Boswellic acid (α-BA), a pentacyclic triterpene compound from extracts of Frankincense, has gastroprotective properties, α-BA decreases oxidative stress and that the Nrf2/HO-1 pathway might play a role in the gastroprotective action of α-BA in ethanol-induced gastric injury in rats.
2. alpha-Boswellic acid can efficiently reduce hyperphosphorylated Tau (Ser404) in STZ-treated astrocytes and decrease ROS generation and promote proliferation of astrocytes through elevating Survivin expression, suggests that α-BA could be considered as a potent therapeutic agent for prevention and decreasing the progression of Alzheimer’s hallmarks in astrocytes; however, more in vivo studies would be needed.
3. Boswellic acid has protective effects against acetaminophen (APAP)-induced hepatotoxicity in Balb/ cA mice.
1. alpha-Carotene has a stronger effect than beta-carotene in suppressing the promoting activity of 12-O-tetradecanoylphorbol-13-acetate on skin carcinogenesis in 7,12-dimethylbenz[a]anthracene-initiated mice.
2. alpha-Carotene has inhibitory effects on proliferation of the human neuroblastoma cell line GOTO.
3. alpha-Carotene inhibits metastasis in Lewis lung carcinoma in vitro, and suppresses lung metastasis and tumor growth in combination with taxol in tumor xenografted C57BL/6 mice.
1. Alpha-humulene and trans-caryophyllene extracted from S.officinalis essential oil can inhibit tumor cell growth.
2. Alpha-humulene and trans-caryophyllene show marked anti-inflammatory effects, probably by interfering with TNFalpha production .
1. Alpha-Chaconine has anti-inflammatory effect, associated with the suppression of AP-1, and supports its possible therapeutic role for the treatment of sepsis.
2. The cytotoxic effects of α-Solanine and alpha-Chaconine were observed immediately after incubation and were constant after 30min, suggesting that rapid damage of plasma membrane causes the lethal disorder of metabolism.
1. Alpha-Cyperone is a promising inhibitor of Hla production by S. aureus and protects lung cells from this bacterium.
2. Alpha-Cyperone significantly inhibited PGE2 production by suppressing the LPS-induced expression of inducible COX-2 at both the mRNA and the protein levels , downregulated the production and mRNA expression of the inflammatory cytokine IL-6.
3. Alpha-Cyperone inhibited actin cytoskeleton polymerization induced by APEC-O78 through down regulating the expression of Nck-2, Cdc42 and Rac1.
1. Alpha-hederin is a haemolytic agent.
2. Alpha-hederin has potential anti-inflammatory activity.
3. Alpha-hederin shows molluscicidal activity and antifungal activity.
