Preface AspartoftheseriesTopicsinHeterocyclicChemistry,thisvolumetitledBioac- tiveHeterocyclesIIpresentscomprehensiveandup-to-datereviewsonselected topicsconcerningflavonoidsandanthocyaninsinplants,andheterocyclessuch asbioactivephenothiazines, phenoxazines, andrelatedcompounds.Thevol- umeisseparatedintotwosectionsmainlyconcentratingonthesetwotopics. There areabundant anddiverse flavonoidswithcarbohydratesandlipids, alkaloids (betalain alkaloids and other alkaloids), phenols (chromones,cou- marins,lignans,quinines,andotherphenolics),terpenoids(monoterpenoids, sesquiterpene lactones, triperpenoid saponins, carotenoids, and other ter- penoids),andmineralsasmicronutritionalphytochemicalsinfruitsandveg- etables of our daily diets. Among these phytochemicals, the flavonoids have specificfunctionalityinrelationtoage-relateddiseasessuchashypertension, diabetes,cardiacinfarction,cataracts,andcancer.Theauthorsofeachchapter inthefirstsectionhavepresentedtheirevidenceinrelationtothemechanism ofthepreventativeandtherapeuticabilityofthecompounds. Thefirstchapter,“FunctionalityofAnthocyaninsasAlternativeMedicine” byNoboruMotohashiandHiroshiSakagami,presentstheirantioxidantmech- anismforanthocyanidins, whicharepresentincommonfoods.Itispossible that anthocyanins may have been used both preventatively and clinically as partofmany“folkloremedicines”worldwideandmayhaveprovidedhealth- carebenefitssincetheappearanceofmankindsome7.5millionyearsago.The reviewwillinformthereaderastotheirfunctionalityandmechanism. Thesecondchapter,“BioactiveMechanismofInteractionbetweenAntho- cyaninsandMacromoleculesLikeDNAandProteins”bySeetharamappaJal- dappagari,NoboruMotohashi,MamathaP.Gangeenahalli,andJamesH.Nai- smith,presentsthebiologicalactivitiesofanthocyanins,andtheinteractions ofanthocyanins withDNA and protein. Anthocyanins might protectagainst damagetohealthbysometypesofharmfuloxidantsthroughvariousmech- anisms such as their antioxidative activity, protein active site binding, and chelating complexformation. The review presents theinteresting interactive mechanismofanthocyanin–DNAcomplexformation. The thirdchapter,“Antibacterial ActivityofArtificial Phenothiazines and IsoflavonesfromPlants”byAsishDasgupta,SujataGhoshDastidar,Yoshiaki Shirataki,andNoboruMotohashi,presentsthatsyntheticphenothiazinesand X Preface isoflavononesare not only powerful antibacterial agents as revealed by their activityintestswithhundreds ofbacteria, butoftenalsoactasantiviraland anticancer agents.

Thefourthchapter,“InhibitionofMultidrugResistanceofCancerCellsby SelectedCarotenoids,FlavonoidsandAnthocyanins”byJosephMolnár,Helga Engi, Nóra Gyémánt, Zsuzsanna Schelz, Gabriella Spengler, Imre Ocsovszki, Miklós Szücs, Judith Hohmann, Margaret Szabó, Lajos Tanács, Péter Mol- nár, Joseph Deli, Liselotte Krenn, Masami Kawase, Hidetsugu Wakabayashi, Teruo Kurihara, Yoshiaki Shirataki, Hiroshi Sakagami, Noboru Motohashi, and Remigijus Didiziapetris, tried to indirectly define receptor-structure in the presence of the diverse structurally unrelated carotenoids, flavonoids, isoflavonoids,andterpenoids.Thisreviewmaycontributetostudiesofmulti- drug-resistant(MDR)proteinsthatbelongtotheATP-bindingcassettesuper- familywhicharepresentinamajorityofhumantumorsandareanimportant finalcauseoftherapeuticfailure. Thefifthchapter,“ChangesinPolyamineLevelsduringCellDeathInduced byHeterocycles”byMasakiKobayashi,HiroshiSakagami,MasamiKawase,and NoboruMotohashi,presentschangesinpolyaminelevelsduringcelldeathin- duced by selective properties of diverse heterocycles such as phenoxazines, flavonoids, and other heterocycles. Natural polyamines (putrescine, spermi- dine, spermine) are aliphatic amines containing two or more amino groups, whichplayimportantrolesinregulating cellgrowthanddifferentiation. De- pletion of polyamine in cells has been known to inhibit cell proliferation or induce celldeath. This review might helpthe studyofchangesin polyamine levelsoncelldeathwheninducedbyheterocycles. Inthesecondsectionofthevolume,N-heterocyclessuchasphenothiazines, phenoxazines, dihydropyridines, and related compounds are shown also to have interesting biological activity including antitumor activity, vermicide, antibacterial activity, and antischizophrenic activity (i.e. chlorpromazine of thephenothiazinefamilyanditsanalogs).Theactivityofphenothiazineand compounds such as phenoxazines and related heterocycles, and also recent bioactivemesoionicheterocycleswillbediscussed. The sixth chapter, “Tumor-Specificity and Type of Cell Death Induced by Heterocycles”by HiroshiSakagami, Masaki Kobayashi, Mariko Ishihara, Hi- rotaka Kikuchi, Yukio Nakamura, Masami Kawase, and Noboru Motohashi, presents the tumor specificities of trifluoromethylimidazoles, phenoxazines, 3-formylchromonederivatives, coumarinanditsderivatives, andvitaminK 2 derivatives andthetypeofcelldeathinduced bythese heterocycles. Thisre- view might beneficially establish a definitive strategy for the exploration of newhighlytumor-selectivecompounds.Also,thescreeningprocessofhighly Preface XI tumor-specific compounds should be introduced before the identification of thetypeofcelldeath(either apoptosis, autophagy, ornecrosis)and thecell- deathinductionmechanism. Theseventhchapter,“AdvancedDihydropyridinesasNovelMultidrugRe- sistanceModifiersandReversing Agents”byAnamikShah,Jitender Bariwal, Joseph Molnár, Masami Kawase, and Noboru Motohashi, presents a com- prehensive review of their synthetic methodologyfor the preparation of the most-activeP-glycoprotein(Pgp)inhibitordihydropyridine.These“privilege structured” families of compounds are potent inhibitors of P-glycoprotein, whicharethemaincauseofeffluxoftoxinsfromthecells.Thisreviewmight beusefulforexploratoryfuturedrug development duetothePgpinhibitory propertyofthedihydropyridines. Thelastchapter,“TheoreticalStudiesonPhenothiazines,Benzo[a]pheno- thiazinesandBenz[c]acridines”byTeruoKurihara,KazumiShinohara,Hidet- sugu Wakabayashi, Noboru Motohashi, Hiroshi Sakagami, and Joseph Mol- nár, presents their quantitative structure–activity relationship (QSAR) anal- ysis for minimum inhibitory concentration (MIC) of phenothiazines and benzo[a]phenothiazines. The MIC values of phenothiazines were well cor- relatedto∆∆Hf,HOMOenergy,andµG.QSARmaybeapplicabletopredict theMICofphenothiazines. Thisreviewcouldcontributetopredictionofthe relationshipofstructuretobiologicalactivity. Itishopedthatthisvolumewillserveasastimulusforresearcherswithan interest in the field of biologicalactivity of flavonoids and heterocycles, and alsostimulatefurtherdevelopmentfornoveltherapeutics.
