The invention relates to a combination of treatments, more particularly a combination treatment for HIV-1 infection. The present invention is directed to the use of bryostatin-1 and their natural and synthetic derivatives for AIDS therapy, in particular to the use of bryostatins in combination with other active drugs such as Histone Deacetylases (HDACs) inhibitors and anti-retrovirals, for the treatment of HIV-1 latency. According to the present invention, we provide a combination therapy for the treatment of HIV-1 latency which employs bryostatin-1 (and analogues) and one of the following HDAC inhibitors; valproic acid, butyrate derivatives, hydroxamic acids and benzamides. While HDACi can be used in continuous dosing protocol, bryostatins can be used following a cyclical dosing protocol. Bryostatins can be formulated in pharmaceutical acceptable carriers including nanoparticles, phospholipids nanosomes and / or biodegradable polymer nanospheres. This combination therapy needs to be used in patients treated with antiretroviral therapy (HIV-1 protease inhibitors, HIV-1 reverse transcriptase inhibitors, HIV-1 integrase inhibitors, CCR5 co-receptor inhibitors and fusion inhibitors).

The present disclosure relates to methods of administering compounds for treating conditions associated with amyloid processing such as Alzheimer's Disease. Methods are disclosed comprising the step of administering a macrocyclic lactone, a benzolactam, a pyrrolidinone or a combination thereof to a subject in need in an amount effective to decrease soluble Aβ-40 or Aβ-42, or to lower total amyloid precursor protein (“APP”). Methods are also disclosed further comprising the step of identifying a subject with increased soluble Aβ-40 or Aβ-42 levels, or elevated APP levels compared to a control population.

The invention provides for the use of protein kinase activators or boosters of nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF) or other neurotrophic factors to treat stroke. Specifically, the present invention provides methods of treating stroke comprising the steps of identifying a subject having suffered a stroke and administering to said subject an amount of a pharmaceutical composition comprising a protein kinase C (PKC) activator or 4-methylcatechol acetic acid (MCBA) and a pharmaceutically acceptable carrier effective to treat at least one symptom of stroke.

The invention relates to the technical field of medicine, in particular to the anti-senile dementia activity of bryostatins and application thereof. According to the bryostatins (BRYS), mouse water maze experiments are conducted, the swimming time can be significantly shortened, obvious improvement effects on acetylcholine esterase (AChE) and acetylcholine (Ach) in mouse brains are achieved, the contents of choline acetyl transferase (ChAT) and malondialdehyde (MDA) are both obviously increased, the effect is significant, and differences are statistically significant. The SOD activity in serum can be significantly increased, P is smaller than 0.01, and the levels of serum reduced glutathione (GSH) and serum glutathione peroxidase (GSH-PX) are increased. In addition, the bryostatins has no obvious influence on the quality of mice and visceral indexes, and it is shown that the toxicity is low. It is shown through experimental results that the bryostatins has significant anti-senile dementia activity and lower toxicity and can be applied to development of drugs for resisting senile dementia.
