CLXXXV.—Harmine and harmaline. Part V. The synthesis …
A series of N(9)-substituted harmine derivatives were synthesized and evaluated for their anticancer activity on a panel of cancer cell lines, their apoptosis induction and their cell cycle effects. The results showed that N(9)-substituted harmine derivatives had anticancer effects. In particular, N(9)-haloalkyl derivatives 9a-9c and N(9)-acyl harmine derivatives 11c and 11d, with IC50 values less than 1μM, were more potent than doxorubicin against A-549 and/or MCF-7 cell lines. Moreover, structure-activity relationships (SARs) indicated that introducing a haloalkyl or benzenesulfonyl group in the N(9)-position of harmine could significantly increase the anticancer activity. The most active compound (11d) caused cell cycle arrest in the G2/M phase, and induced cell apoptosis in a dose-dependent manner.
Proof of the “reality” of this type of experience is also evident in the shaman-revealed herbal combinations that are either divulged or sold to pharmaceutical manufacturers who then synthesize, refine, test and manufacture the product. As stated earlier 74% of today’s pharmacopeia originates from this source.
It is a pale yellow solid that is soluble in organic solvents
In order to search for novel leading compounds endowed with better antitumor activities and less neurotoxicities, a series of harmine derivatives were designed and synthesized by modification of position-2, 7 and 9 of β-carboline nucleus, and their cytotoxic activities against human tumor cell lines were investigated.
So, ingesting l-tryptophan to increase serotonin levels, a candy bar to increase the amount of tryptophan getting to your brain and naturalplant material containing 25-50 mg harmine/harmaline to block MAO, all at thesame time, might cause your pineal gland to synthesize substantial amounts of5-MeO-DMT ().
